Propane Trouble: Vapor Lock? Frozen Lines? Just this morning we woke up to find that our furnace wasn't...

Just this morning we woke up to find that our furnace wasn't lit.
We use propane to heat and cook beside.
The stove wasn't working properly either. The flame would desk light (its an electric ignition pilot), burn for only a few minutes, later sputter or fade out. We could light the pilot on the furnace, and bring the blower going, then it'd purely go out.
It's taken several hours in a minute but we've finally gotten everything working again.
Does anyone know what might have be wrong with it? Vapor lock? Frozen lines? (it's 20 degree here in SW Michigan) ??
Water filter systems for showers?
Answers:    Regulator freeze-up most imagined caused by moisture contained by the supply chain. Report it to your supplier because if it have happened to you, it's probably happen to others as well. Adding methanol to the supply secure usually alleviates the problem. The supplier should be able to bring up to date you right away because they will have multiple call with the issue at duplicate time. If you are the only one who call in than most plausible the problem is in your system. From your description of the events I conjecture it's safe to right to be heard the problem is with your regulators. If the satchel is freeze up or something else will be up to your supplier to figure out.
