Weird ? re: putting truck into reverse while moving forward

This one's for the true ECM gurus...

Is there a piece of code in the ECM that will kill the motor if the truck is moving forward at, say, 5-10+ mph and the shift position sensor suddenly sees Reverse? I was driving to work and the little e-clip that holds the shift cable in place fell out. While the tranny actually stayed in Drive, the shifter might have moved into the reverse position at the center console. The result is that the truck died. It wasn't until I came to a complete stop that it fired back up and drove normally. I have since fixed the shift cable issue and drove it home without incident, but does anyone know if such a piece of code exists that would make it do that? Otherwise, I need to look around as to why my truck wants to die sporadically.

Thanks for the help.

Absolutely not. There is no shift position sensor for one, and for two I drove around with my truck stuck in drive for two LONG years and when people would ride my ass Ild put the shifter in reverse so the back up lights would come one to get them to go away and it never stalled out. Even did it sitting at lights. Only thing your truck "knows" is P/N. Must be something else going on. I can tell you that when my cable was broken I could put the shifter in neutral and the rpms would come up a hair, but that is because of the P/N safety switch.

No code to kill it, the ecm does know if it is P/N or D but that is it.
