I have an older 30KW
need to calibrate the main control board. 83089. also is it overspeed or overcrank? if the board does not see the right rpm or is blow a certain threshold it will think it has not started yet and shut down on overcrank.
Generac over-speed fault
check your frequency of the ac, if this is high, then adjust the rpms.
If that is fine and it is shutting down, check overspeed adjustment on control board if it has it.

Generac guardian rv generator starts and runs but after a couple minutes the power stops.....generator still runs??
Usually the generator will shut down if the ac is not present coming out of the generator. You stated that it still runs but no power on the output. Check your breakers first to make sure they are working properly. Depending on what board you have you can check to see if ac is present getting back to the board as well. If your board does not have this then they are using the frequency as a safety disconnect feature. That would lead you back to the regulator or loose connection or..dirty slip rings if this unit has brushes.
