Salutations folks Ive been running my blitz for some time now but the last 2 times at the track my car will shut down for just a second "throttle and steering" then come back and it dose this on and off. some times 5 min or more inbetween. I noticed a snapped antenna on my receiver so i replaced that but it diddnt fix the problem. Here is what im running.

Havoc 3 ESC with Ballistic 8.5 (running temps 120 after 20 min)
ACE 1313 servo
Spektrum dx2.0 radio with sc300 receiver.
Hobby People 5000MaH 2cell 35c lipos

People at the track seem to think something on the esc board has come loose but ive also heard people say it could be my dsm1, although i have a hard time believing that since its worked perfect for so long.

Please help, im going insane.
