clogged vent.. I don't know how your unit is vented.. I only know it should be PVC.. Does it bring air outside in from the same vent it exhaust through ?? or, Does it have 2 seprate pipes ? If 2 pipes 1 is exhaust 1 is intake

Well it's not getting any air for some reason .. Won't burn without air.. Look for obstruction in the intake
