What heater is this? Model and manufacturer?
Is it getting another call from the thermostat when it does this?

I would second this. I had a 20 year old furnace start acting up. I did my research online and replaced the induction fan, then hired a pro to come clean the burners and do what they could. It never worked consistently I ended up going two winters without a furnace before replacing it this fall. My new furnace is so much nicer, quieter than my old one.I think it might be the issue of the age already. Since the heater is kind of old, i'd say this is the first sign toward it reaching kaput.
