Just enjoyed reading your fuel pump issue thread. Noticed you said "Lakeland". If that is Florida we are your neighbors in Auburndale.
Those in tank fuel pumps have given lots of misery to folks. It was no fun having the issue while living in the tall hills of California. Running out of power there was a real pain. Once it started acting up on flat ground it was easier to diagnose. Running the generator always seemed to contribute to the symptoms as did running with less than half a tank of fuel. I surmise the fuel pump got hot.
