propane powered generator

[firemanpat2910]

I know its not a tractor but want to draw on this wealth of knowledge. I am helping troubleshoot a RV generator made by Oran. It starts fine runs good but runs for 30 minutes and shuts off. if you start it back up it runs good for 30 minutes then shuts off. anybody ever had this issue? any ideas? Thanks.

I need to know is it fed by liquid or vapor? If it's liquid it could be the regulator, they have a habit of gumming up with a black tar like substance.
There is a very good troubleshooting forum over at smokestak forum under the onan generator thread!
