Fired the genset up this afternoon. It started easily after priming and ran smoothly for 20-30 minutes. I had turned both A/C's on while it was
running and right before it quit, it sounded like it was running out of gas.

I know it's not a good thing to shut down a generator under load and I think it has damaged itself now that it did so.

I turned off the A/C's, tried to re-start the generator and it took several tries, firing and dying immediately then finally starting and running
smoothly. I gave it 5 to 10 minutes then went to turn the A/C's back on and neither came on. The generator sounds like it has a load applied but
nothing is happening with A/C units.

What died now?

Check the bridge rectifier.

Check the 120 volt breakers.

Sorry, meant to post that I reset all the breakers inside the coach.

That's on the genset, right?

Regarding the first problem, Examine /replace every inch of fuel line feeding the generator. Mine had an almost invisible split where it was clamped
to the fuel pump barb sucking air. Regarding no AC output, flip or push breaker on top of Onan itself. If no 120V get a meter and meter the line side
of breaker. If still no, the bridge rectifier may have failed under the plastic air intake grill. This is more envolved if you are electrcally
challenged.

Yes, it is inside the bell frame and if it is a 6kW (NH) in a 26, it is easy to get to. Not so in a 23.

Matt - waiting for parts today

Thanks John, everything on the fuel system has been gone through recently, I'll find why it stopped after I diagnose the electrical issue. I was
drawing a blank of the bridge rectifier which is why I posted.

If you have an ohmmeter and are not color blind, you can be talked through the bridge rectifier test. Even color blind can do it if able to tell the
difference between the red test lead and the black one.
