You didn't run out of propane but you did run out of sufficient power (battery current) to light the electronic ignition in the furnace.
Something like this happened to us in Alaska. Woke up in the middle of the night to the furnace turning on and off, and the LPG alarm sounding then quieting. The battery wasn't good enough to keep the furnace running. It'd stop then lose a little LPG when trying to re-light, setting the alarm off. About then the battery had rebounded enough to run the furnace again for a few minutes.
Do notice: I said "not good enough" and we in fact replaced the battery after that trip. This coach is a 36-ft Jayco fiver. Equipped with one battery, not sure there was space for another.
