This is similar to the problem I have. Sometimes if I go WOT at about 70 the engine goes into this limp mode, no pedal response. We narrowed it down to an issue with my ECM though, because I get code p0606, PCM internal performance problem.

I bought a bluetooth ODB2 adapter and the torque app so I'm going to piss off the neighbors this weekend and see if I can get the pedal to go limp in the neighborhood while reading codes to figure out what's going on.

The minute I do it away from the house on purpose truck probably won't come back to life for me. lol

I've got the p0606 also, looks like it's time to find a tuner and or new PCM from my research so far
