WED4815EW1 Dryer overheating?

Hello! My Whirlpool dryer model WED4815EW1 has begun stopping mid cycle for 10-15 minutes and then starts again on its own. I cleaned out the lint trap as well as the vent hose to outside. There was almost nothing in either, so I don’t think it is clogged. It is 1 year old. What else can I check?

Thaddeusgardner, when the dryer has shut down, is there 120VAC on the outgoing light blue wire of the push-to-start switch? Also, does the drum rotate smoothly?
