fuel problem, the float in the carborator is stuck, if you tap on the carborator bowl it will probably get freed up.if not take the bowl off and spray the insides with carb. cleaner.

SOURCE: I have a 7kW generac

check the rubber boot for the carb. I had the same problem and found that the boot was cracked. I replaced it and now it runs fine.

I had this same issue with my NP 50G. I replaced the oil pressure & over heat sensor and fuel filter but the problem still existed.

After that I took the fuel bowel off the carb which had some dirt in it. Sprayed it with carb cleaner and that solved the issue. Hope this helps......

May be early onset of the electric fuel pump failing as it gets hot. Be sure to ensure the fuel pump is pumping fuel to the carb by pulling the hose off the carb and watching for adequate flow. A faulty electric fuel pump can often only show symptoms or act up after it is warmed up. Sometimes it may run for 10 or 20 minutes and just shut down. Check for fuel flow immediately upon stalling if this is your symptom. Mine would shut down after 20 minutes and not restart for awhile. I pulled the hose off the carb immediately and noted there was no fuel in the line and it would not pump fuel while holding the start switch on either. If you are mechanically savvy you can disconnect the hot wire the positive wire (red) leading into the fuel pump and connect it with 12 V and see if it pumps fuel out the hose also, but be careful to capture the fuel coming out the hose). Once cooled down it pumped fuel in a weaker than normal stream, but when hot after 10 or 20 minutes it quit pumping causing stalling of the generator. Replaced the fuel pump (and new filter while at it) and everything worked fine again on my 1995 Onan. Much stronger fuel stream noted too from the hose.
