HELP! 2007 chevy 2500 hd classic Stalls

[cris2for]

Please HELP! My friend has a 2007 Chevy 2500 HD Classic 6.0 That while he's driving it just shuts off. Then it dose nothing when he tries to restart it. No noise no nothing. the dash lights all come on just no cranking or trying to crank. There is a code U0107 Throttle Actuator control loss communication. It seems when first started that it has to get really warmed up then it quits. After that he can just have it running in the driveway a few minutes & it will quit after the intimal warm up. It's like something is getting hot/ I'm hoping someone else has had this issue & knows where to have us look. Not sure the code has anything to do with it quiting. A garage put a new PCM on it but it didn't fix it. Thanks

I'd check all wiring and connections for looseness and corrosion. It sounds like a bad connection that needs to be addressed before anything else.
