Default studdering

WHen first started my car drives fine. M6 cheatr cam...
After a WOT run or after it warms up it seems to lose it's tune. It wants to die at anthing less than 75% throttle. I tried to clean my battery cable because its corroded. Can this be the tune. It seems like something electrical. It still runs like a bat out of hell at WOT.

It happened while on the dyno. The tuner said the screen went flatlined during about a 3500 rpm hold before activating nitrous. Could a vacuum leak do this. The tuner said that the ground wire on the back of the head may be loose.
