I know questions on this generator have been beat to death, but I have been pouring through the posts on the forum and I can't seem to find my specific issue previously posted.
My QuickSilver Generator 7.5G starts fairly easily and runs smoothly. Handles the load of both AC units and with a new impeller and recent cooling system flush, has a good flow of water out of the exhaust.
The problem: If I start it when the engine is cold it will run for a period of time, sometimes several hours before it begins "hunting" or "surging" with rapid throttle fluctuations for about 15 seconds before shutting down. If I try to immediately restart, it will crank but not stay running. If I let it sit for an hour or so, It will start again and run for a shorter while, maybe an hour before shutting down.
Question: If it is overheating...would it "hunt" or "surge" like this before shutting down? I assumed that it would just turn off if it overheated. If it is not overheating, what would cause it to behave this way after running smoothly for several hours?
Thanks to all in advance the information I have learned from this forum has been invaluable.
