The GTB doesn't actually just die. It allows you to crawl around on part throttle(It restricts to like 1/4 throttle or less) to get you back into the pits. But the car still moves... once it cools down enough then it goes back to full power.

Have you checked the esc when this is happening? Which lights are flashing on the unit? they'll tell you whether it's a thermal situaiton or a rotor dectect situation...
