Please HELP!!! Stalling issue! Also p0320 and p1687 codes!

I have a 2000 jeep grand cherokee. When I first start it it will run fine but once it gets warmed up and I come to a stop light/sign or stop and go traffic she will stall why is that? And when she does stall everything stays on like radio, HUD ect it's like you don't notice it unless you look down and see the Rpm's are at zero or you hit the gas and nothing happens. So what I do is put her into neutral and turn the key and she starts right back up every time! Now I have replaced the IAC, the computer, and the crank shaft position sensor. So I'm totally lost on what to do next?? Plus I have turned the key back and fourth 3x and these two codes popped up p0320 and p1687. Would these be the cause of the stalling issue and if so what do I have to change to fix them??
Thanks for your time and hope to hear from you all soon!!

P1687 - No Cluster Bus Message
P0320 - Ignition/Distributor Engine Speed Input Circuit Malfunction

I'll let someone else drop in about this. I'm not very familiar with WJs yet.
