I am having an issue with my truck. Starts fine when cold and runs great when started. the problem is once the motor is hot and at operating temperature and is shut down , It does not want to start again. I have to turn the key for about 3 or 4 minutes till she fires . Once running its great again but only if I don't shut it off. If I do the same thing happens . Anybody have a solution or a starting point to figure this out. I have had the injectors checked over and they are all good. Thanks
