1996 Dodge Ram P1391 diagnostic code

I am working on a 1996 Dodge Ram pickup with 318. It is running ragged when it gets hot. When you slow down on stop the truck cuts off 2 - 3 times or more before you can get is going again. :banghead: I hooked up the OBD machine and got diagnostic code P1391 Intermittent loss of CMP or CKP. We have replaced the crank shaft sensor, cam shaft sensor, distributor cap, and rotor button. It ran fine for a couple of drives and now right back to the same thing. :screwy: Any suggestions of what to look for now would be greatly appreciated. Thanks.....

Have you ran the computer on it sense you have seen the CEL come on again?

I found this, I do not know if it will help but it does mention the PCM may need to be replaced and the CKP may be installed incorrectly.
