Sporadic loud noise coming from engine after stalled going down the highway at about 80

What is your question?

2011 Chevy Colorado 3.7 liter i5 crew cab 4×4 automatic I was running my truck down the highway at about 80 miles an hour past the semi when it seemed as the transmission slipped let off the accelerator got back in the other lane as the truck dies pulled over cycled ignition off restarted the truck no check engine lights no nothing pulled back onto the highway got about a mile down the road seemed as the transmission was slipping again truck dies and won't restart due to a dead battery put a new battery in the truck cranked it over started but sounded as though a camshaft bearing or something in the top end of the engine it had spun or went out only code it's throwing is a camshaft exhaust sensor code but makes a hell of a racket any thoughts

What makes this problem better or worse?

Don't know only ran it long enuf to check codes

How long has your 2011 Chevrolet Colorado had this problem?
