My WAG (Wild Azzed Guess) would be flexing of the frame could have put extra tension on some wiring or connector and momentarily interrupted a important ground or caused a plug to wiggle slightly in a socket.
If the headlights went on and off then it's probably something to do with the battery cables or a ground.

I'm thinking that this one will be tough nut to crack, I wish you the best of luck.

Nope died about 15 feet from the driveway. Was slowing down and downshifted with the phone in my hand when it died and gauges started to freak out. The LCD display was displaying different wording the usual. The speed numbers were circling and the instant mpg were circling. It was really weird to say the least.

My Guess WAG Wink Wink would be an internal short in your "NEW" Battery. Id pull it take it to the autoparts store and see what happens after a load test.

ok that might explain why when all lights are on with A/C and I am at a stoplight with turn signal on and alt is at lowest output the voltage gauge moves with the beat of the flasher towards VERY low voltage... maybe??

Yes and/or a crapping out internal voltage regulator inside the Alternator. Again as the boyz stated above a bad cable can cause all this havoc as well. When you pull the battery so can inspect the cables as well. Is this a top and side post style battery? If both make sure the positive battery post is not hitting the under side of the Cruise Control servo bracket.

Side post battery. No interference noted.

Will inspect cables again.

If that ever happens to me (200 amp new alternator) I am in real trouble

This is however a BIG clue

Dynomite:

does ur gauge move at all with a load on the system at an idle?

My engine parts are all over the garage floor and my new alternator is not installed yet....but I do not think (with stock alternator) it did before I took the engine all apart

I would go out right now and check that for ya if I could.

If your idle speed is very low...yes it might do that with everything on.

Or if not....GOLDCYLON I think is on to something

He is on to something because my lights are HID's. So under really low voltage they will start to flash/blink. It happened once before when i had a vacuum line from the MAP sensor come loose and it was running horribly. Lights would flash with a lowwww idle. But why would the starter not engage for 10 mins, then start right up like there was no issue?

I am thinking alternator/starter going at the same time.

Had a starter issue earlier this year. Just both symptoms showed up at one time last night.
