Dryer will only dry like two loads then, it will quit mid-load and can't get to restart. The dryer vent has been checked and is clean. Lint filter clean and vacuumed out. If you try to start the lights will come on but go off as soon as you release the start button. No error codes. Seems like dryer is getting too hot and needs to cool off. Sometimes, it will not fully dry when on sensor dry and other times seems like it overheats.

What parts do we start with? Or what do we check?
