apm hitting ppm failsafe mid flight

My skywalker's apm tends to crash after a running for awhile. the airlerons lock at a certain angle, the rudder deflects and all of it leads to a spiralling crash. I can't understand why suddenly the power goes off to the board, (the imu lights go off, but the APM has power) has this happen to anyone else? will try to get a video of it happening. 

the last crash took the toll on the plane. this happened after a fresh install of code, and calibration. 

either its software issue where the failsafe is triggered due to a crash, or a hardware issue where power is lost to the board. 

any insights will be greatly appreciated.

    Sounds like a brownout. Maybe your ESC/BEC is not up to the power demands of that platform?
