Just recommissioned for spring and I need to troubleshoot the generator

Starts normally. New plugs. Oil level is good. Coolant level is good. Water is coming out with the exhaust.

Runs strong for about 5 minutes then it starts stumbling, recovers, and after 5 or 6 stumbles it dies out. Restarts and runs for another minute or two and then does the same again.

Fuel filter issue? I hate working with the fuel system as any spilled fuel is a hazard, so going down the list of other things it might be before I check the fuel system
