Car Problems explanation and video inside

[Venom351R]

Went to the track this morn to run the Test and Tune and try out the new Slicks. The day was a disaster for me anyway. When the car gets to 4,000 RPM's at WOT it starts to break up, lurch, hitch and buck. It was doing it when I was trying to run and it does it on the street as well. It drives fine but at WOT at 4,000 RPM's it just goes to hell. I suspect that it is electrical but Im not positive or what it could be. Also the car has had a problem of randomly shutting off while driving. The radio goes dead and the car loses all power for about 5 seconds then it all comes back and its fine after that. I suspect that these two things are related. Here is a video I took just before I got home, you can hear the car hitching and bucking once it reaches 4,000 RPM's

what distributor do you have in there?

Problems with a MSD box? Or your chip isn't making a good connection to the ECU?

My car would loose power and almost die, and I think it ended being a connection problem with the SCT chip. I removed and reinstalled the chip and it kind of worked itself out.

Also, mine was breaking up around 5800 rpms, and that ended being a problem with the rev limiter in my Crane ignition box.

could it be a TPS sensor? mine was breaking up for awhile like that but i cleaned the MAF out and it fixed that problem, but i still get a skipping/bucking every day
