Furnace Won't Stay Lit

Furnace ignites but almost immediately shuts down. The diagnostic leds suggest burner ignition issues. This can be a mechanical issue or can be a venting issue. First time this happened, I tore into the furnace, checked the ignitor, checked electrical, checked drain hoses. End result was snow clogged vent. This time I confirmed the diagnostic leds and went outside to check on the vents. Sure enough, the intake vent was covered up with snow. The furnace was not getting enough air to keep the flames lit so it turned off.
