car shuts off for no reason...

I got an automatic start installed on my on my car this winter and it has a sticker message to alert mechanics who go under the hood, I've had no problems with the automatic start. I got it inspected and got a wheel alignment in the last two days and on the third day the car just shut off on me at a light. No lights came on prior to it shutting off and it started right back up and drove off like normal! WTF! I only mentioned the work I had done to see if that trigger the problem. Im so scared to drive it now bcus I dont want to be far and it cut off. Anyone know what it could be!!??

Your post has been moved to its own thread, as it had nothing to do with abs.

Sounds like a passlock issue, does your security light come on or flash ?
