You have replaced all of the fuel lines, replaced fuel filters, etc. But how about the fuel pickup pipe. Sometimes they have an inlet screen or check valve that plugs. I had a check valve at the top of the fuel tank plug with goop and after cleaning it out the engine ran fine.

Good suggestions. I will do the sensor disconnect next time.

I thought about the tank pipe exit myself, but it is a messy job to take it apart and hard to get to it. Plus, there is a Racor dedicated to the generator between the tank pipe and the generator's fuel hose. The Racor is full and looks very clean. I just replaced the filter recently.
