Check the low oil sensor.. But, most of the Onan's problem stem from the control board. There are aftermarket replacements if needed.. Check eBay..

Okay that I could go to but didn't really fine anything in there to help me.But thanks for the site I put it in my favorites for future refer. Well so far we have tryied the carburetor took it off after checking it and finding ever thing clean in there. Took the oil filter off and disconneced the oil solenoid and found nothinging there it worked. new oil and new filter has been put in the generator. next thing were going to check is take the front cover on the front off and check the wiring if we don't fine anything there.we close it up take out the unit and carry it to a Onan dealership.

Start with checking the oil. Too much or too little will shut it down. If the oil is OK next unplug the remote start button. It is to the right of the panel that has the built in start button. squeeze the top and bottom of the plug to unlock it. Sometimes the remote switch is bad. If still shuts down, crank the gen. and hold the button down and see if it runs as long as you hold the start button down.

Thank you all for your help and Ideas so far everything we have checked and done is not working.These are the things we have checked.
(!) checked oil okay.
(2) unpluged oil sensor, wasn't it.
(3) unplug control board wasn't it.
(4) checked gas line to see if carburetor was getting gas,okay
(5) checked spark plug it was okay,.checked plug wire to see if it was getting fire ,okay
(6) took carburetor off clean it , didnt see anything that would cause it to shut down put it back on, that wasn't it.
made sure everything was pluged back up and everything together.
Only one thing left to chek is electrical.

What model genny do you have? Is it a 5500? If so and you are sure the oil level is correct (the RV is on level ground?) and the carb bowl is clean, I would check the fuel pump itself. Check the vacuum side to see if it draws fuel and the pressure side to see that fuel is in fact flowing to the carb. The pump for mine is located on the frame rails below the gen compartment, and while you're at it check the electrical connections for the fuel pump. Hope this helps.

Did you try holding down the start button after it starts to see if it will run with the start button held down?

I always press and hold the stop button for about 15 seconds and then start button until started.
If your genny will start then kill sounds like it is trying to start loaded which it can not do,possible transfer switch contacts may be energized, manually turn your breakers off at the generator then try to start.
Happy RVing,james

Yes we have held down the start button and it will run but you can't hold it down long. We are not level does that make a different!

It is a 5500 Onan and we have held the stop button down. My brothering law is a deisel mechanic and he said we have checked all the dummie things that sometimes we forget, and just because he's been a mechanic for 28 yrs does mean he know's everything he can still learn somethings. It is not pluged up to the house or I think it wasn't pluged up to the house at the time he was checking it.
