Onan Marquis Gold 5500

I have a Onan Marquis Gold 5500 in my 2011 Cyclone. It is 2 years old. It has always been started every month and run for 30 minutes, and I have always used gas stabilizer. When I start it now, and it runs great but every 30 seconds it starts to cut out like it is starving for fuel. It runs great fr 30 seconds then cuts our for 5 seconds, and runs great again for 30 seconds. This happens over and over. I ran it 2 hours today and this happened the whole time. It only has 12 hours on it. Any ideas?

    I would check the fuel filter first, then the fuel lines to see if air is getting into them, then the fuel pump. Check all connections from the fuel tank to the generator.

    Does it give you the trouble code? If the light blinks 3 times push starter button once & it will blink pause & blink again. The 2 digit number will be the trouble code.
