What is causing my truck to stall n die when I come to a stop.

What is your question?

It is intermittent in as much as it happens throughout the day, cold or warm, but not every stop. It will die even if the stop has not been completed. When it does not die the idle, 700 rpm at rest, will drop to 200 or so then immediately return to 700. I have replaced the TPM and the EGR valve, both having set off the check engine light. This issue does not set off any warning. Also observed is the feeling of some binding or stiffness in the rotation in the drive train from a cold start, like it is in 4x. Can't tell if binding continues after some initial driving warm up. I need ideas to check for failings in the system.
