Engine stopped on main street. Had to have someone help push it off the road so traffic could resume. Engine would turn over but not start. Took about 10 minutes then it fired right up like nothing was wrong!

My daughter took the car to go pick her boy friend up and came out to the car for it not to start! I thought she was lying just to stay out longer. Except the nightmare was actually true. The anti lock theft system caused the car to shut down. it's a head ache with out the car. I am scared to take it to the car dealer because they will tell me something totally different other then what is really wrong. Can anybody help solve the problem with out cheating me?
