truck keeps dieing after hard pull

[TCAV89]

hey guys i have a quick question. last week i entered my truck in a truck pull and went up againt a mildly built 7.3. i had my dp tuner on 80E (no tow setting yet) and my truck in 4x4 low. when i laid into it my boost was around 26 PSI and my egts were around 1250*. my turbo started to shudder alot so i took my foot off the pedal for a second and when i did the truck shut off. it immediatly fired right back up but if it wasnt for that i wouldnt have lost it also did the same thing when i was pulling a buddy out of some deep mud and was getting on it trying to get him out.

Anyways, will turbo shutter cause my truck to die when i take my foot of the throttle?? my shudder wasnt mild, it was extremly loud. im gonna put a wicked wheel and ported housing on it to fix the shudder but is that what is causeing my truck to die or could it be something else. im just trying to prevent this from happening again. any help is greatly appreciated!! Thanks

I remember when my oil cooler was shot, my truck would die after I'd get on it. I replaced the oil cooler and it's gaskets, no more problem. It may be something you should look into.
