I have replaced the crank sensor and speed sensor. Put a new fuel sending unit in. So, the fuel gauge sometimes works and when it does the truck will start and run but stalls after a while. I cleaned the cluster and checked all relays. Everything is good on that end. Idk what it could be.

It sounds like the PCM is bad, I would send it out for testing here is the location so you can check it out, you can get a preprogrammed unit by searching Google or Ebay. here is more information:

The P0725 error code in an automobile diagnostic reading represents an issue with the "Engine Speed Input Circuit".

Check out the images (below). Please let us know how it goes.
