sometimes If I turn off the Motor, my car wont start until a couple of minutes. i was told that its a case of vapior lock. just recently, my wife was driving and it just shut off while driving down the freeway!!. it eventually starts up but only for awhile. Any suggestions?

not vapor lock. have your wife get the car scanned for codes. they do it for free at autozone, then get back to us with the codes
