Generator quits while engine running

Our generator has always worked fine, and still does if we're stationery. Recently, we needed to run the generator while driving. On two occasions, the generator quit for no apparent reason. Has anyone else experienced this and is there any known cause for this problem?

Could be a vacum in your tank while driving and not letting the pump for the genny suck the fuel out of the tank. Try to drive with the gas cap loosened a little. Also if it does it when the engine is running and sitting still just take the cap off and let them both run and see if it stops.

That may be one reason. I have noticed a similar problem with my generator except that mine is propane so the vacuum issue would not apply.

Yes it would only be for diesel and gas generators. Yours could still be something stopping the flow of propane. Still need fuel-air-and spark to run.

This is a long-standing / well-documented problem between Onan and Xantrex--do a search on this forum it you want/need the details. There is no known OEM solution for the problem created when you have the Onan running and start the Cummins. The work around is to shut-off the charger function on the Xantrex once you start the Cummins, or vice-versa, once you start the Onan. The Onan will work fine as long as it doesnt sense a multi-charge from the Cummins alternator and the Xantrex charger. The Xantrex also has a "hot-start" function for the charger so if you shut-down the Onan for any reason, you will have to shut-off the Xantrex charger again when you restart the Onan. The work-around process is a bit like running your tummy and tapping your head but as long as you get the Xantrex charger shut off before the Onan sense the Cummins alternator line charge, you will be ok......good luck....

Mine does this when the main fuel tank drops anywhere close to less than 1/3 of a tank. But you probably know this already, I'm thinking. Just an idea. Your rig might have a tank designated for the generator. Not sure.
