okay this has happened to me twice already My car would start and I would drive it awhile...I would turn it off to run in and do something real quick. (now both times my heater was running while i was driving) I go to start my car and nothing..I got power to everything fuel pump primes car turns over but doesn't start....I let it sit there for a minute or two try it and again and it starts...could there be something faulty I need to look at??? any ideas
