Car wouldn't start, waited 10 mintes then started

What is your question?

My daughter started her car this morning, drove about 1 mile and stopped, turned off the car. Came back out to start the car and it would not start. Had her check all the usual (in park, steering not locked,etc) and still nothing. After about 5-10 minutes she tried it again and it started. Mechanic is saying it could be something with the Theft block? anyone know anything about this? He's estimating 200$ for the part plus labor...
