Printer Crashes at the Beginning of a Print
I see a couple likely culprits for a hardcrash like this

problems with the power supply. If the power supply does not provide enough voltage an/or current to the board, this can lead to a lockup of the board.
temperature issues of the board. If the board overheats, it could fail to execute properly, leading to abort. make sure that the board is not overheating.
faulty firmware. recompile your firmware and reflash it.
