I will condense this as best I can. Last November, on the day we were travelling to storage facility, after dumping stabilizer, I went to start the Generator to get stabilizer in system... no power, no fuel pump action, nothing, and when I went to check fuse, the fuse cap was broke off due to deterioration. It was cold, we needed to get moving, so I never attempted a repair.
Forward to today. Purchased a new thru panel fuse carrier, and while I was removing the old one, (it was severely loose), pulling off one of the connectors, it touched metal and sparked strongly. Since everything was off, I couldn't figure that out. Double checked, and I hadn't shut the power off to house battery! Went back and carried on, but if either contact touched the framework, there was a gentle spark again.
It was a tough job getting the holder in place with the lock nut behind and getting the 2nd connector attached because of all the other wires from the loom in that area. But, finally, got it together/connected, tightened in and happy to report, the fuel pump activated, and the unit turned over to start, but it kept dying out promptly. I knew I was on the edge for gas tank level, so filled up with gas, returned home, primed the unit and happy to say, it fired right up. Let it run for about 5-10 minutes, no load, then went to turn it off from the remote start inside, and it would not shut it off, hmmm, went to the unit and the off switch would not shut it off there either. Uh Oh. Weirdly, in about another ten minutes, it stopped on its own. I decided to start it again after a bit, fired right up, and I pulled the fuse out hoping that would have an effect, did not, and once again, after a while, it just died out. I am a little worried about any subsequent start ups, as maybe my luck will run out on it shutting down.

Screaming out for help, any thoughts???

Thinking now, maybe I shorted one of the toggle switches with the spark????

How many hrs and what yr? What chassis ? Better and more opinions will follow.. so my suggestion is you may be dealing with more than on problem and you are trying to solve them as one.. just guessing.. so what I would try.. is put a cheap inline fuel shut off valve made for mowers.. that way you can shut off fuel .. and it will have to stop..
Next one is tricky.. why does it just seem to stop on it's own.. look in my old post on onan generator.. you will see I have learned from the great members here..
When it dies on it's own.. you can sit there guessing.. or take steps to eliminate 50% of what the problem is.. fuel or electrical.. I go in great detail in my old posts..
Good luck and keep us posted

So, during a deep internet search, I found a thread with an exact situation as mine. I did not mention in original post, when I try to stop engine with the switch, you can detect a slight change in "pitch" or sound from the genny, Maybe even a slight drop in revs. When switch gets pushed back to start mode, the "pitch" disappears.

This is the forum post referring to what he found... loose wire at one of the two coils!

Sounds like some work getting there, but worth a try.

The genny safety circuits usually go to ground shutting the genny down/ not the same as a short. You may shorted digital switch relay on control board I would for sure inspect the board and connections Also remove the remote harness plug try only from the genny. Lastly I would remove stop switch wire on genny as well as remote harness plug or attempt to jumper switch closed . With electronics off could be open or closed. Flightsystems Inc.repairs or has replacement genny circuit boards. The shutting down after may or may not be related to the short.
