I have 2013 Ford F150. I can go out and start it up in the morning and it starts great. After I drive it for 30 minutes or so and I stop at Kroger to pick up Doughnuts and Sushi (lol), it won't restart. If it sits for 30 to 45 minutes...it will then start. I have taken it to a mechanic and they get in it in the morning and start and restart repeatedly and then they call me and say, "It starts just fine"... Theg checked the battery and the starter and say they are ok. I am really stumped and need help from Scotty the Auto God.... Thanks
It has a failing camshaft position sensor. When the defective sensor gets hot it stops working.
The computer only needs the input from the camshaft position sensor to establish the TDC of cylinder #1 during start up. After that it knows relative to the crankshaft position sensor where #1 cyl. TDC is.
You start cold fine. As you drive your defective camshaft position sensor gets warm and stops working but your computer doesn't need it anymore so you drive along fine UNTIL you shut off your engine and try to restart with that warm/now inoperative camshaft position sensor.
Without its input the computer doesn't know where #1 cyl TDC is, so it can't time your ignition spark and fuel injectors and you can't start the truck until the sensor cools down and starts working again.
Could this also cause engine light and/or low oil pressure light?
It won't cause the low oil pressure light to illuminate.
