I did not see this post so answered your other post about the start button first.

This is a different set of symptoms.

It sounds like the motor is overheating. It then trips it's internal thermal protect and you then have to wait for the motor to cool down before it will restart.

Can have a number of causes.
: Perhaps there is too much drag on the motor caused by a mechanical problem with the drum. Try turning the drum by hand in the correct direction, it should turn fairly easily. You may want to try this on a couple other dryers to get a feel for it.

: Perhaps the seal at the back of the blower is shot and it is blowing hot air back at the motor. Try running it with no heat if it now rums OK then this is a likely cause.

: The motor may be on it's last legs.
