I have had this problem from day 1 in a brand new THOR. It has been to ONAN twice, and both times they diagnosed, and replaced bad fuel pumps, this with less than 100 hours. It will run from 2-6 hours, quit, and not restart for hours.
ONAN says something in way it was installed is problem, THOR denies it, and I, the customer of both, get screwed in stereo. Kind of like Harris batteries all over again.
Right now no one has a solution, just typical finger pointing and responsibility denial. THOR also tried blaming ethanol in the fuel causing vapor lock. ONAN I am sure has had enough years to engineer their generators to work on 10% ethanol. At least, most seem to.
If anyone hears of someone getting a resolution, please share with all of us.
