Pinched/crimped wire, bad injector, ect. It can't be anything big.

Thanks for the suggestions, anyone else have any other ideas before I dive under the hood this weekend? I really need to figure this thing out, tonight on the way home I was getting on it a little in 2nd gear and the car basically shut off and back on by itself. :-/ Thanks in advance.

As far as I know there aren't any mods on the car, other then a CAI. The car completely shut down electrically tonight while driving it, the indash tv folded up the gauges shut off, everything..just like the key was shut off. It's really starting to worry me, I replaced the coil pack and wires/plugs and double checked them, and everything looks fine. Should I try reseting the computer? And would it work by leaving the key on (without the car running) and pulling the PCM fuse for a few mins? I heard this works fine on LS1's and heard the same about my car. What could be causing it to misfire AND lose all power electrically?
