Q: Security on 1999 Pontiac Grand Am

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
At random times, the car will not start and the security light is flashing. If we wait 5-10 minutes the light goes out and the car will run. Any recomendations?

Chances are you will need to replace the ignition lock cylinder. The lock cylinder contains the security system sensor that picks up the signal that the key is in the ignition. With out the correct signal from the passlock sensor the car will not start or will start and die.
