Ford 460 Class A question??
Hi my name is Dennis. I am hoping I can get some suggestions on fixing my problem. I have a 1996 Damon Intruder with a 460 Engine in it. This motor has performed flawless for 9 years since I have owne...

New information.
Went out and did some tests listed here. I used my volt meter to get exact reading. Motor home set One full day setting idle not trying anything at all.
Before Trying to start it I tested the red/light green wire going into the coil. 13.68 volts with key on. At this point I tell my self the engine is going to start. Plugged coil back in and it fires up immediately.
Runs for 2 minutes and dies. I start it back up and it fires right up. I checked fuel pressure gauge while it was running. When it first started up it went to 39 PSI and dropped to 30-32 PSI kind of jumpy but never went below 30 PSI. Pulled the fuel regulator hose off of regulator while it was running and PSI went to 39 and held steady.Hose was dry with no signs of wetness of any kind. It did run a little rough when I unhooked the regulator hose.
MH run for about 2 minutes and died again. 3rd time it fired right back up as before.
Run for about a minute and died. Fuel pressure when it died went to 39 for just a second and then dropped to 36-37 PSI and held there. Will not restart at this point.
Unplugged coil inlet wires again and tested it again(Red/light Green wire) and it had 13.68 volts. Reinstalled the plug to coil.
Put my spark ignition tester on and had no spark from coil output. (coil is brand new).
I noticed a red wire coming from coil plug in to a little grey plug and black wire coming out to a little black fuse like item that bolts onto the head right beneath the coil. I think it is called an ignition coil insulator. It is some type of fuse item.I read somewhere it is for radio interference from engine running but not sure.
So here is where I'm at. What do I do now?
I think the ignition module is bolted on the left side of the air induction piece where the 2 hoses come from the air filter. If I unplug that can I test it for power without harming it?
Sorry this is so long but wanted to make sure I had all the info I have gathered up to now.
