If a vehicle shuts off while driving down the road. then restarts after about 10 minutes, its a bad crank sensor or the wiring to the sensor. A check engine light may not turn on. If the light is on. You can take it to any auto parts store to have the code read by a scanner for free. Auto-zone, Advanced ETC. Its worth a try! But first check the fuel pump relay, It may be getting hot and shutting down pump. Try swapping a relay of the same type, if it is ok, thats the problem. Hope this helps!
I would look at the fuel injectors. Sometimes they can leak down after a short stop flooding the engine. After about 30 minutes the fuel evaporates and the car will start. Any check engine light on or other tell tale signs? Sometimes the fuel trim numbers will be off to compensate for a rich condition. What all has been replaced?
u need a good car electrician to check the faulty electrical circuit that goes on and off at times or have ur car diagnosed electronically using an electronic scan tool to check if ur having a faulty signal from ur relays or your on board computer/ it seems to me the real culprit is ur ignition key cylinder that when not properly set wont give electrical connection to power up the starter....its definitely an electrical issue....
replace fuel pump relay. check all fuses to ignition and pcm .make sure they are not loose. check coil wires make sure they not loose.look at battery if you have the ac delco seal battery make sure green eye still there .if its black have battery check out.
