May be a gummy carb or something else causing back pressure.
Oil level would be my first check also or maybe a temperature sensor. A generator may backfire at shut down so hard to say if that is a symptom or not. How is the propane level? On the edge of empty? Any fault codes? At 12 years the ignition system might be at the end of it's useful life. Spark plug wire(s) could be arcing to ground.
Before you make the drive to an RV shop call the local small engine repair shops or the whole house generator service techs and find out if they will work on it. Considering this is their bread and butter you'll get more bang for the buck and probably same day service.
