Your passlock security is activated or failing. Many things can cause this. 1 or more of three things. The key chip is bad, the ignition cylinder that reads the key is bad, or the TDM (Theft Deterrant Module-computer that reads the info) is bad. All of which can shut down your vehicle by keeping it from starting, or shutting down while driving. For more info, read my "profile" section on this site. Just click on my name.

Turns over won't start 2000 grand am?

If your security light is flashing, then you have had what is referred to as a "bad timing cycle" with your Passlok security system. Turn the key to the ON position, and wait until the security light stops flashing - This takes exactly 10 minutes.If the security light WAS flashing, then the 10-minute trick is only a temporary fix - You will need to have your ignition switch replaced.
