Second time using the RV. Fired the water heater on propane, it ran for about 10-15 mins then the flame slowly tapered off like we were running out of propane. The heater would attempt to refire but only produce a small lazy flame. After the unit sat for a while it would refire fine. Connections are clean, the orifice on the valve assembly is clean, tanks are full, all other appliances fire fine at the same time. The controller is behaving as I would expect it would.

The Trailer is a 2006 Outback 28KRS, the water heater is an Atwood GC6AA-10E

Any ideas? I have never seen solenoid valves fail like this.
