80b shutting down ?

[stampy]

Ive had my quark 80b for about a month now and resently (as soon as i put it in my ruslter i got) it has been shutting down at random for some reason i dont know if its thermling or what but it shuts down for a little bit and doesn't respond to throttle imputs the steering works but thats it. i give it about 5 sec or so and it starts working agian but as soon as i give it some throttle and take off it does it agian. as far as i can tell its not getting that hot, 140ish maby, i can hold my finger on the metal heat sink for almost 2 full seconds the motor on the other hand is hot enuff to sizzle water latterly could that be the problem way the controller is shutting off maby? :032:
