I have a 2001 dakota 4.7L. It starts right up and runs fine. Once you shut it off, it wont start for about a half hour or so. I have changed engine temp sensor, , , the computer and no resolve. Also changed . I am lost, any help would be greatly appreciated

 

Need to see what's missing when it won't start... Spark, or fuel. Does the pump run when you try and restart?

 

The fuel pump does kick in when I try to restart. For the spark, I dont think I have the proper tools to test for that.

 

Just because you hear the fuel pump it does not mean the injectors are firing. You need a "noid" light.
For the coils, you could pull a coil off and see if the plug fires.

 

may be a fuel pressure leakdown issue...after the hot soak...try starting it in clear flood mode or put a fuel pressure guage on it and check for pressure leakdown.
