I just bought a 2002 Fleetwood and the generator will not stay running. I have remove carb. disassemble and clean, complete service oil/fuel filter. The fuel tank is 1/2 full. When the starter is turning over it will run smooth but when I release the start button the fuel and the ignition shuts off. I am thinking it is a electronic relay or something but trying to see if any one has answers or a common problem. Model is 5.5 HGJAB-901A Thanks
