I am inclined to agree with Dave. I had the EXACT same scenario on my last coach and it turned out to be the fuel pump. Easy enough to check. If you can find the fuel line going into the carburetor, disconnect it and get a bucket. Hold the fuel line over the bucket and press the generator start button (on the upper left side of the generator) to the PRIME direction. It should pump fuel freely and with vigor until you release the Prime button. If it pumps a little squirt or two and then dribbles, chances are good that the pump is toast.
