    Does the furnace have a pilot light. Carrier uses what is known as an auto pilot which has 3 wires, white, green and yellow that come out of the pilot assembly. It doesn't sound like the burner is running long enough to trip the main limit so I would suspect the auto pilot is dropping out voltage to the main gas valve.
