From your post I am assuming the motor runs OK you just loose the heat.

Could be and air flow problem. Usually this is a vent problem.

Undo the dryer from the exhaust
Run a load
If the load dries correctly then you have a vent problem.
Clean/check the vent system. Make sure the outside louvers open fully.

If you do not want lint in the house.
Take a pair of pantyhose, put one leg into the other and attach this to the dryer exhaust.
Leave enough room behind the dryer so it can blow out like a windsock.
Run a load.

Both the above will allow you to check the air flow and temp.
Also the above is NOT recommended for a gas dryer due to possible carbon monoxide problems.

Also air flow can be affected by:
Loose/dirty blower wheel. Clean and check.
Lint filter coated with fabric softener residue. Clean with soap and water.
Poor tub seal felts.


Could also be you have a loose connection somewhere in the heater circuit that is opening once heated up.
