Tons of problems! Rv complete shutdown while driving?!

[Fla904]

Heading through North Carolina and my rv completely shut off when I stopped at a exit ramp. It was running fine and then all a sudden it completely shut off. It took me a few minutes to crank it back on and now it's running down the road. Two days ago it took a few seconds to start which has never happened before and when Ideling it was kind of shaky. I went and changed the fuel filter, oil, oil filter, and had all fluid levels checked. The battery's are showing all charged and were also checked as fine during the oil change. The ac quit blowing air out today (hot and cold) nothing comes out of the vents on any setting and then shortly after the rv completely turned off when I stopped at the stop sign and took a while to start back up. What's going on?! I can't afford to break down this far away from home!

I think you need to get to a shop soon. The problem won't get any better the more you drive. When it shuts down do the dash lights, radio etc. also go
of? If you can try to restart as soon as it shuts down you don't have a ground or loose cable. I had a similar problem with a dual fuel tank system. The truck would run fine on the one tank at high speed but would die at idle. Needed a new fuel pump in that tank. Your AC is a completely different problem'

If it's a fuel issue I'd be looking at that too. Doesn't that happen when things get too hot?

When it shut off the dash lights were still on and the service engine soon and battery light came on. But now it's all off and running fine. Next time I refuel I guess is when I'll find out if it's gonna shut down again. So frustrating, just spent 200 on the recent tune up.

The OP is not reporting that he lost electrical power so much as I can tell.

Only that the vehicle stalled when he stopped, and it took a while to restart.

This sounds like a fuel starvation problem, or a stuck open EGR.

The A/C issue is most likely a separate issue, older Fords all have the vacuum loss airflow goes to defrost outlets thing.

That doesn't say much, ..

If I could say more I would.. my opinion is this will have to be diagnosed in a shop.

But, if it's fuel starvation, why is there no electrical anywhere? Even if the engine is off, with the key turned over, the fan, lights, radio, everything should still be running or on. All power is dead to everything ... more than just the engine shutting down.

If the battery cable was loose, there would still be electric power as the vehicle alternator will still put out a charge to the rest of the vehicle. Although it's not a good thing to do, it is possible to run a vehicle with no battery once it get's started. (Newer vehicles, not so much, as computers will shut the vehicle down). But older vehicles still would operate if the battery disconnected. With all electrical shutting down, its not fuel or battery only. Could be a combination of stuff hitting all at once. But for everything to quit, the problem has to be near the source of the electrical output for the entire vehicle .... engine and all accessories.

Keep brainstorming guys! Let's get this guy home!

Look for a vacuum leak. Vacuum opens the doors on your heater and you say nothing comes out of the heater.

This is not something that can be diagnosed over the internet. You need to listen and look.

Did you check all your battery connections for corrosion and make sure they are clean and tight?
Also check for a loose ground wire. I've noticed over the years that bad connections can cause a lot of weird problems.
Always check the cheap easy things first.

Last time I checked all the battery connections were fine. I just had it serviced two days ago and the mechanic said everything looked great. This is a real bummer I can't afford any major issues. Not to mention the generator issues which I've been having. I really just want to make it home and I'll take it to my local mechanic but breaking down in North Carolina will be to expensive for me right now. If it's a fuel issue is that normally a expensive fix? Does it sound like I can make it back or do u think ill break down again? Now the ac is working again.. Go figure. No idea what's going on.

Do you have a battery disconnect switch in the vehicle....I had one that looked fine but upon dismantling it fell apart in my hands...replaced and works fine now.The only other thing I can think of is a loose battery connection or ground.

[sch911]

It really sounds like a fuel issue to me. Vapor lock. Restarts after it cools down a bit. Once up and running will go but stalls when you stop. Seems like a classic case.

Malfunctioning computer board, loose fuse in the fuse holder, loose wire under the hood, loose battery cable? Could be just about anything. Sorry, I can't help more. But it's electrical, need to look where the main electrical output starts, sounds like a loose fuse to me, the main one for the entire vehicle or the wires attached to the holder?

That doesn't say much, do you think I could make it home to diagnose this? Anyone ever had this happen?

[Fla904]

Also, it runs fine at high speeds but shuts down when I slow down or stop. I have maintained this thing meticulously. I don't know what this could be?
