That sounds like the motor is getting hot, and shutting off on heat overload. Try running it by taking off the vent hose at the wall and leaving the vent hose attached to the dryer, and put a panty hose around the end of the vent hose that goes on the wall, so you can catch the lint. If it works fin e, then you either have a clogged vent to the outside, or there could be a big build-up of lint inside the dryer. So if you pop the top up, and take the front off, down below is the vent housing, that is where that dryer builds up lint.
