Need help Motor/ESC keeps dying

[Specter]

Hey guys hoping someone can help, my motor keeps cutting out randomly for no apparent reason, i've checked all the wires, i've checked for contact with the frame, i've resoldered the plugs, i've swapped the motor for a new one (same type-RCer 3300kv), i've swapped ESC's (not the same type-quark33amp to CCPhoenix35amp). All this and the problem continues its doing my f@ckin head in any suggestions would be good.
She was flying great only a week ago!
Cheers
