Default 6.0 loses power

I have a 03 6.0 with 139k on it. A old man owned it it was bone stock. I straight piped it and put the bullydog triple programmer on it since it'll be in Hawaii. FYI-I am gettin ride of the bullydog and gettin a sct. i ran it a week with the programmer. after gettin off the interstate i stopped at a stop sign when i took off it barely went anywhere even when i put it to the floor. It happend 2 more times that night. Any help/advice would be greatly appreciated

Any check engine lights?

Also u say it did it two more times that night. So when it did it it only did it at the one light and then drove fine after you got up to speed? Or was it sluggish though out the whole drive? Any smoke or other abnormalities?

Didn't see any smoke that I could see it would jus hesitate for a couple seconds right at a high idle like then itd pick up and do just fine. Each time it did it that night I was stopped. Almost like the fuel pump wasnt pickin up at first

How does it start? Hot/cold effect it at all? If you have access to a scan tool, i would run an injector buzz test and a cylinder contribution test. Have you checked the EGR valve yet? I hesitate to throw out any "could be this" statements cause thats no better than half the hack a$$ stealership service writers out there.

Have you removed the Triple Dog to rule it out? I would discon both batteries for about an hour to ensure the compters reset. I've pulled stuff iff if mine and had to do this.
