Power Vents are very complex and have had some nuisance shutdowns when the pressure safety switch mistakes windy conditions for blocked vents.
We have had some windy weather so that could have been your problem.
Power vents are a cheap way to vent the burner exhaust but they sure can cause a lot of problems if not working properly. I know a lot of burner technicians who refuse to work on any burner that doesn’t have a chimney.
Next time this happens shut your furnace down with the safety switch and then turn it back on to see if it will reset itself.
You want to be careful how many times you try to reset the burner because it could buildup fuel in the burner and cause an explosion.
