The battery is a low pro protek and its got about 20 runs on it. I have tried other batteries such as my racers Edge packs. My mind tells me it's the motor because that is the newest part I have. Also just a little more info is it's not thermal either. Hottest it comes off at is 168 motor and 105 esc. It does though seem to do it more after a few laps in. So I did think batt or thermal but like I said I tested both of those possibilities already.
