Was going to change the oil and filter on my Onan 50 amp gas generator today that is in my 2003 Holiday Rambler MH. I haven't run the generator in a couple of months but after priming it it started, stalled and restarted. It ran ok for about a minute and then quit. I tried several times to restart it but it won't start. In the owners manual it talks about code but I have no idea where I would look for that. Could someone offer some suggestions on where to look for my problem? I would like to get it running before storage so I can get some fuel stabilizer in it.
Thanks in advance.

Items to check:
#1, Is your MH fuel tank more than 14/ full?
You should store the MH with a full tank anyway to reduce water condensation, and add the appropriate amount of Stabil when filling the tank.
#2, The genset fuel pump may have quit.
#3, To view the flashing light that equates to a code, hold the stop button down for a several minutes. I think this energizes the fuel pump to prime the fuel system too.

That's the best my memory can do at this late hour, sorry.

Per your advice Ray I checked my fuel level. The gas gauge said I was a little above 1/4 tank but I decided perhaps the gas gauge was a little off so I picked up 8 gallons of gas and dumped them in. I primed the generator and sure enough it started and stayed running. Learned something new that I didn't know. Got my oil changed and I'll top off the gas tank when I drive it to it's winter storage home.
Thank You Ray and Hawkeye for your help.
Love all the advice people give on this forum !
