deal with this all the time. When gen shuts off, place couple paper towels under carb, open bowl drain screw, see if much fuel comes out. If only couple drops, or none, then either fuel pump is getting hot and quits pumping, or control board is getting overheated, and quits sending power to fuel pump. Usually displays fault code 36, but have seen other fault codes if control board is problem. There is third condition that will cause these symptoms, that being hot air is being recirculating to air intake and gen temperature in housing is getting so hot that gas is boiling in fuel line and carb, causing shut down. This problem seems to be much more common last couple years, and I can't prove it, but I think fuel boiling point is lower than used to be with the crappy fuel we have to use these days
Thanks Bounder39zman. You nailed it. Minimal fuel in float bowl after it shut down. Compared it to a properly filled bowl after restart and it only had about 1/10 of the amount as normal. Now I just have to find a reasonably priced fuel pump lol.
Replaced the fuel pump and it fired right up. I realized that I was still on shore line so I shut it down after about 10 seconds and it would not start after.It would not even fire; just crank. I checked for fuel at the carb-good, spark-good. I used some starting fluid in the air inlet and it would run on that so I pulled the carb and inspected and blew out all the passages, reinstalled and still no go. Today I disconnected the wire leading to the solenoid on the bottom of the carb and using a jumper wire I could get it to run but only for about 1 second at a time. Any ideas? Thanks in advance.

Once again I ask, is the light in the start button flashing? If so, there's a trouble code stored and should be retrieved and decoded to reveal the reason the generator is stopping.
Has the OP ever revealed the model of the generator vintage so that an educated answer can be given?
