This is in a 94 Northstar (Texson) TS 1000 with 3 way frig. Owned about 5 yrs. Propane side of frig has worked fine apart from blowing out while driving. Got it out of storage for first trip this season. Hard to light the propane. It's got the push button thermocouple gas bypass and piezio ignition with a viewing prism. Lights on first or second spark with a moderate flame but flame then dies out even with button pushed. Finally stayed lit after about 20 tries. Same problem each time it went out when driving. Very hard to stay lit but once it stays lit long enough to warm the thermocouple it runs. It seems like it's running out of gas even with the button pushed. I think it has enough oxygen since the flame is blue and not yellow. When I got home I removed my wind baffle and the OE cover and watched it while my wife started it. It started perfectly fine then. No evidence of dirt or cobwebs once I removed the covers. Anyone have any ideas or experienced this? Almost seemed as if the gas push button provided enough gas initially but then stopped passing gas.
