I should have mentioned, this happened about two minutes into a race. I did turn the radio on before the receiver though.
I find it hard to believe that it is the motor as well but I'm starting to run out of options.
Just for the heck of it here is a picture of my speed-t. May it rest in pieces.
one thing I noticed looking at your pic is that you're running a receiver pack..........
why? 
the other simple thing is that you don't have your motor wires from the ESC to the motor "braided" - and the castle motors are notorious for voltage spikes that cause glitches, and even they recommend (along with most BL motor manufacturers) to braid the wires to eliminate the possiblity of interference to the radio.
finally, you have all your wires just
flopping around in the truck. not a good thing, and "could" lead to all kind of issues
