Car starts cold and runs fine. Drive a wys, shut off nd let sit for while, turns over but won’t start. Let sit a while longer, starts right up. New crankshaft position sensor fuel pump, emergency shut off switch, fuel filter, and cleaned MAF sensor

This can be many things, such as the ignition switch or PCM power relay, fuel pump relay, bad MAF sensor, (cleaning wont help) etc. What we need to do is isolate the system that is not working when the engine stalls, please go over this video to help get us started.

If we don't do this we will continue to throw parts at it hoping the find the problem. If you don't mind that we can take educated guesses at it which would be the things I mentioned above. Please go over this guide and get back to us. Ken
