Onan 4000 just shuts down on load No tripped breakers

We have a Onan 4000 in a Class C Minnie Winnie that just stops when its under a pretty heavy load. It's still under its rated amps but just stops. No breakers trip. I don't find anything in the manual...

Its a possibility. It has circuitry that turns it off if it cant keep the frequency and/or voltage in spec.

A breaker will trip only when amperage has been exceeded. Your genset cant make enough amps to get there.

Could be carb, fuel supply, dirty air cleaner or a bad controller or connection somewhere.
