Scotty..Just done a lot of work on my  6.2ls non DoD in my 08 Yukon. Lifters, timing chain, vvt, replaced the cam sensor cause I broke the original. Vehicle runs great but after warm up it dies at a stop. Will always  start back up if you hold the pedal to the floor. No codes or CEL. Used my bidirectional scan tool and see no problems. Only replaced the crank sensor chasing this problem but didn't fix. Any suggestions?

You got bad fuel injectors. Clean them or replace them.
