dryer shuts off after 5 min then u can restart and it will complete cycle

[LIST=1]
*]When dryer starts it will run about 5 minutes and then shuts off. The dryer heats as normal, does not seam to be overheating. After about 3 or 4 minutes you can start the dryer and it will run the full cycle. I checked the vent and it was clean and the door works okay.[/LIST]
