2000 Alero, 2.2liter, 120,000. Occasionally the car won't start and the security light begins to blink. Everything locks up. Engine cranks but won't fire. After waiting 10 mintues the security light goes off then the car acts normal and starts. This was happening on an irregular basis, once every 3 months or so, now it is happening more regularly. thanks

Sounds like it could be some type of anti theft module.

The same thing happened to my 2001 Alero. I had to replace the ignition switch, which has to be bought from the dealer because of theft deterrent system. Heavey key rings can cause this.
