Help please!

Sorry for posting this again I meant to post here first but i posted in the Texas discussion thread first.

So I was driving my Z today and as I was about to merge on the highway I accelerated into redline with my 3rd gear.
I shifted right at fuel cutoff and then slapped it into fourth however my car turned off completely and i loss all power.

Pulled over on the shoulder of the service road and then attempted to turn on my car.. did not work.
Opened the hood and inspected everything, no loose connections and no funny smells..

Reset the ECU with the accelerator pedal and then on my third try it turned on but the car was vibrating like CRAZY and RPMS were fluctuating between 1.2k and 400 and it was shaking inside the cabin, so I turned it off and got it towed home..

Taking it to Nissan tomorrow..
Im so confused..
Anyone know what happened?

Thanks for the help
