For starters would wait for a shutdown then check the state of the sensors (coolant temp, oil p, exhaust temp, etc) to see if one of those are tripping a shutdown sequence. otherwise as Capt Brett indicated you can get real deep trying to troubleshoot control issues and or intermittent problems like an electric fuel pump going bad. A service manual and DVM are pretty important for troubleshooting. If you turn to a professional make sure you find someone who has experience with generator controls.
Thanks! I have changed out most of the sensors, this electric fuel pump seems to come up quite often as a possible problem, maybe I'll just swap it out just to see what happens. I figure it cant hurt, and besides its a 2006 so its 12 yrs old.
FYI I always like to double back, and if I found a solution, to let the next guy know. We think we have it fixed, he changed all the stuff we could mechanically, fuel pumps, sensors, fuel filters etc etc. Finally we switched out the electronic board, and I think we have it fixed!! knock on wood!! It ran for 4 hrs yesterday, with out missing a beat, and put out good, stable power! I think the board was around $140.
