Make sure the wire connections on the fuel pump are tight.  Mine did something similar while driving and one of the wires was loose, tightened it by squeezing with pliers and it worked great.

Ok, I am green as grass. Now I know that I need to be looking for an electric pump, not a mechanical, unit. Would I find it in the generator compartment?

BTW, are you familiar with  Todd's coach? This genset is  pneumatically "propelled " out the front. Sure glad Todd spent a lot of time with me. I never would  have found that button.
