Hello , my name is ***** ***** I will be assisting you today . this type of stalling is usually caused by a failing camshaft position sensor , or a failing crankshaft position sensor , or a failing PCM . I am pretty sure that this is a failing PCM . I say this because you said that 1 you have to wait an hour before it will start , and 2 you said that there are no trouble codes. If the camshaft position sensor or crankshaft position sensor were bad, you should have a code for them. Since you do not, I am pretty sure that this is a problem with the PCM and that you should replace it. By the way , the PCM is the vehicle's engine computer. Ask your mechanic to check that and consider replacing the PCM

I hope that this information is helpful and if so , would you kindly take a moment to rate my service using the just answer star rating system ? I would really appreciate it . I will still be able to help you out even after you rate me

Thank you !

Chris
