I would check two things. First, replace all the fuel filters. Second, observe fuel shut off solenoid while the generator is misbehaving, sounds like it is not holding in. If those two dont cure it, check electrical connections to fuel pump.

I’m having a similar problem..  will start but barely run.  And craps out after a couple seconds..  put new fuel filter, and water separator on it today..  same thing will run for a few seconds maybe 15-20 and then die. It never gets revved up..  I tried holding what I thought was the “fuel solenoid” on but it didn’t change anything. 

Is there a fuel off solenoid that may be getting stuck??  Maybe the fuel on solenoid is going bad??

Ran good last fall like it was supposed to
