Not sure where you are traveling at this time but I'm having the same problem with propane at home. But mine is only when outside air temps are below 20 deg F. I have two 100 lb tanks outside using for the gas stove. I spoke with the local propane dealer who told me they can add a shot of methanol to the tank the next time I bring it in for a refill. Says it happens quite often when temps get cold. If you are in cold country you may be having the same problem. Until I need a refill he told me to heat the regulator with a hair dryer. That works long enough to cook a meal but is a PITA heating it up when its in the single digit temps.
