Posted recently about having an issue with my 01 jeep Cherokee dying randomly and security key light coming on. Well at work it died after about 3 minutes running and wouldn't restart. Security key light stays lit and odometer reads "no bar". Had to tow it out next day. Ran long enough to get on trailer then died again. Have tried to start a few times and if it does start it will run for about 3 min then die and not restart. Checked codes and getting P1694. Replaced cps and no change. Also new battery. I'm really thinking its pcm or skim related. Was thinking about sending pcm off to get skim delete. Any ideas?
