05 f250 crank but no start

[kp38]

whats up guys, I was driving home sunday night and while coming to a red light my truck just shuts off out of no where. I tried to crank it back up and nothing, it turns over but does not start. I got it to my house and pulled the codes. The only code I have is p0606 (pcm processor fault). Would that be the cause of this problem? I checked voltage on the ficm with key on and cranking, it stays at 48v the whole time. Cleared the codes tried it again and still no start, but the code did not come back. any input/ideas would be greatly appreciated.

Thanks, Kyle
