onan generator problem. help!

wouldn't you know it?
I'm supposed to leave tomorrow afternoon for 3 glorious days on my land in Nacogdoches Texas, and have run into generator problems while doing my pre excursion prep.
The generator is the 2.5kw onan in my my 2012 arctic fox 1150.
Standard propane unit, and the the few times I've used it, it's been flawless. I've even made sure to go out and run it for an hour under load every couple of months, just to keep it lubed as instructed. So far it only has about 14 hours on it.
Now, when I tried to start it, it fires right up, runs about 5 seconds, then, just peters out.
I've checked everything I can think of including blockage on the air intake hose, but that's covered with some sort of sock/foam screen already, so I don't think that's the problem. It just sound like it's being starved for fuel. I do have full propane, in fact I checked the stove and it fires right up, and the fridge is running as we speak.

Anybody have any similar experiences and if so, any advice????
thanks

  • Are you plugged in to shore power?

    Generator needs to sense a load for it to keep running. If not it shuts down.

    If you are connected to shore power then no load is applied to generator circuit

    I agree. Check the oil level. You may have consumed enough oil during break-in to drop below safe operating level.
  • Ran into a simaler problem. Wouldn't start from inside could get it started out side. strange as it may be all I did was blow out the air filter and all around the generator. Found two things wronge dust everywhere and a birds nest. We also had 14 hrs and the AF-990 is a 2007. Also check the tanks as Bedlam said wont hurt. I checked both tanks and it would run fine once started out side after blowing it out it works perfect now even starts inside. One way is to make sure the stove lights easy and the fridge will fire up at the same time. Not a fool proof way of checking the requlator but if the others work so should the generator.
