It was Double T RV Service.

dose it try to relight after the 15-20 sec.? you don't have a voltage problem or it would not lite at all.sounds like it is not sensing the flame and shutting down the gas valve.

Yes, just make sure you have water in the tank if not when you plug in to an outlet or run generator it will send power to the element and burn it out

reread your message, are you saying you have the LP shut off and getting pressure out of the lines?
