Jeep Stalls after driving for about 15 Minutes

I leave work every day for lunch and drive about 10 minutes to home. I stay for about 20 minutes and leave. Here is my problem: When Im leaving to go back to work, my jeep will start and the check eng light comes on. Then when I put it into reverse to back up and let out clutch it sputters and dies out. I can usually get it to run fine after about 5-25 tries at starting it, and it seems to only do this after being driven, shutdown and then restarted. Ran a scanner on the ECM and the codes were "below recommended minimum voltage" issues with the TPS and MAP sensors. I replaced the MAP sensor, and TPS and still having the same problem. Any ideas on what else to try?

Its a 1994 XJ, 4.0 HO, 5-speed manual, 216,000.

Is the TPS adjusted to the correctly? Also maybe check the CPS, I had a problem where my jeep was running just fine, and for what ever reason it just shut down, after doing a bunch of tests, I saw that the CPS wasn't center on the mounting thing, Replaced it not a problem sence.

Sounds like a CPS to me.
