Sounds like something in the engine governor system and fuel system. I am guessing it runs off the main MH tank. First thought is to run some diesel fuel system cleaner through the system. It would take a good amount. then run the genset long enough to pump through the genset fuel system.
Genset may not be coming up to operational RPM until the governor sees a heavier load.
It does run off if the main tank. I have a fuel system cleaner in it already. I always add a bottle of diesel additive to the tank when I park it after a trip. I fill the tank and add the additive. It runs great under a load. I’m going to run it with a load and then start reducing the load a little at a time until everything is off and see if it dies then. Thanks for the input. If you think of anything else please pass it along.
