Thanks for all your inputs. By the way, a neighbor has the same heater I have and began experiencing the same issue I have as the freezing rain arrived.
Now that you have added the 'Freezing rain' info.,....
Spark electrode is getting wet, grounding out and therefore NOT lighting propane or NOT being able to transmit 'flame proving' signal so it doesn't stay lite.
Check for water getting in thru upper lip on door panel, via exhaust vent/shield or blowing in around door panel
Evidence would be WET area on/around spark electrode/burner area etc.
