No service faults at all. It never stops running, just throttles up and down but smooths out when a load is put on it.
Check the frequency and voltage. I love my Kill A Watt for that at $20.
You are experiencing "hunting." I get it with my Onan 6500. Here's the manual:

On page 8-20 you can see the governor. You want to move the spring a bit farther (one notch will probably do it) from the centrifugal shaft to reduce hunting.
