Truck Dies?

[04Z71Blackout]

Ok so I have a 2004 silverado z71 with the 5.3 and I got in it about 4 days ago started it up and it idled super low but not rough been doing that since. 2 days later I was in the church parking lot sitting still and it died so I started it back up no problem other than the low idle and was moving about 5 mph and it died again and this similar type of thing has happened probably 8 times since and I nor my mechanic can figure it out. No codes good fuel pressure even on start up always around 60 psi we are stumped and any help would be greatly appreciated

Does it run find besides at idle? Have you tried cleaning the throttle body?

It could also be the IAC is loaded up with carbon.

it does run fine otherwise, battery and alternator are good, have not cleaned anything as far as throttle body or maf, and not sure what iac is?? thanks for the help thus far but it has got me stumped.... maybe the throttle position sensor or idle sensor?

IAC is idle air control
