I have tested the problem as it may relate to the gas cap. I tried 3 different caps, and the problem remains the same. However, if I remove the cap, the generator runs fine. Further testing also shows that within 3 minutes after replacing the cap while both the RV and generator have been running without problems for 10 minutes or so, the generator will begin to starve for fuel and die.
It looks like you may have nailed it.

I think that I have finally resolved the problem. I took the MH to a repair facility in Phoenix, Oregon. They found that all three of the charcoal canisters were plugged, which created excess vacuum in the fuel tank and therefore chocked the fuel supply to the generator. Those canisters are spendy suckers though.

Generac Generator Issue

Make sure the cartridge fuse above the fuel primer switch is making good contact. The fuse cap holder may not be making good contact either with the fuse or the body. The generator will shut down immediately if contact is lost for only an instant and will not restart automatically. Found the fuse cap holder loose on ours one time, and learned ever since to make that the first thing to check if it won't start.
