Why does my G35 Coupe engine just shut off out of nowhere?

What is your question?

So I drive a 2005 Infiniti G35 Coupe and I will be driving down the road and just randomly my engine will just die. It acts as if my key just went one notch down like the click before you turn over your car, and when this happens my whole dash lights up like a Christmas tree. After that, I'll pull over and go to turn it over and it wont start and I have to give it a little gas and it turns over, but then my slip light and traction control light come on and I cant turn them off. It seems it's an electrical problem but I'm just baffled and cant think of what the problem might be. Can anyone help me out with this? Oh and my temp gauge likes to go up and down when I accelerate.

What makes this problem better or worse?

I can't tell.

How long has your 2005 INFINITI G35 had this problem?

About a month.
