You do not have to worry about the heater section (thermostats etc.), they will not shut the motor off which is what I think is happening
Could be a number of things:
-
Motor overheating - The motor has a built in thermal protect/cutoff that opens if the motor overheats but this takes a couple minutes for the motor to cool down for it to reset so from your description of re-starting it is low on the list.
-
Door switch - Could be it is just making, the clothes hit the door, the switch opens and the dryer stops. Bend the switch actuator a little so that it actuates more positively when the door closes. Be careful you do not want to break the actuator.
-
Start relay - Could be weak or have pitted contacts and is dropping out during a cycle. I do not know how you would check this other than replacing it. If bad, sometimes you can hear them buzz but not always.
-
A bad timer contact
-
A loose wire - Low in probability but a possibility
