I checked the "usual suspects" (the real easy stuff) first.
Clean air filter. Spark plug looks nice and clean and proper gap.
Oil level full and plenty of gas.
I started it again and turned on the AC. Voltage and Hz was nice and steady 117 +/- and 60 +/- under load.
After 10 minutes it started wavering and finally died.
Started it again and with no load voltage and frequency look good but it only lasted about 5 minutes.
Because it starts and runs good I was thinking it might be heat related. But I don't see a high temp switch??? Maybe something in the control circuit breaking down ??
But even though it runs for a while I guess I shouldn't rule out fuel system problems because it does go up and down for a while before it quits.
Maybe I will take the air filter off and shoot some carb cleaner thru it.
When the weather cools down I will try Handbasket's suggestion. And I will pick up a new fuel filter to change at the same time. Been under there enough for today.
Rodger I do have the service manual. I guess I better start looking the wiring diagrams.
