Engine Shorts Out - Only on a Dead Hook We are curious if anyone else has experienced something similar where my son's '01 T/A will essentially shut off for a split second, every one of the dash lights illuminates and the gauge needles go to zero - but only on a dead hook at a drag strip, it will not do this on the street since it just blows the tires off. Also, if you leave at 2k at the track but only give it half throttle, everything functions as normal. All of the wiring has been checked, and rechecked - and grounds. Fuel tank is full. The car has been tuned multiple times, 420HP to the tire on a Mustang Dyno, no engine codes. Hopefully the video attaches...(it won't, says it is too large of a file), so here's a screen shot from the video

I once had my car shut down all the gauges on a left hand turn into my road. Only did it one time.
My 08 Ford Van had a gauge issue and it turned out to be the connector going into the cluster.

My 2010 Silverado used to do this time to time. Be driving along and for a split second would loose all power. Lights and everything would go off and back on immediately, the engine even would keep running. Ended up being the battery cables. Something with internal corrosion that you couldn't see by visual inspection. Replaced several years ago, no problem since.
I was all for the battery post comments above, but I have also had a ground wire on the back of the head break loose from the ring lug. During normal driving it would make contact and and be fine, but as soon as you hit a big bump or launched it would shut the car off momentarily. Check those grounds....

Thanks all, good advice. We are going to replace both battery cables, something is not happy when the car rocks back at the hit - and at this point, its less about the $$ to fix it vs alleviating the frustration!
As soon as this thing does hook, I bet it spits the factory rear - but we'll deal with that when it happens.....

This is my son's car, and he's touring Germany right now with his High School German Class - he will hardly be able to contain himself, he'll want to race this thing as soon as he gets back!
Thanks everyone!
