dryer shuts off after 15 min

My Maytag runns fine for 10-15 minutes then shuts off…dead…after cool down will work again for another period and then again shutdown.
Exhaust duct clean.
Any ideas?
thanks

Make sure there is no less than 240 VAC at the wall outlet.

Take the dryer apart.

Make sure there is no lint buildup around the drive motor. Check the blower wheel. Make sure it’s not sliding around the shaft.

If it would not help, replace the drive motor.
