I had the same issues with my 2001 Jeep Grand Cherokee about 2 months ago. In the end it was the PCM.
Problem started with gauges not working. Then starting/stalling issue. No a/c, windows occasionally would not work. After researching a lot of forums and blogs I tried several things. Cleaned battery terminals. Tested several modules for a short (window, MIC etc..). I had 2 problem codes, P1686 (no SKIM bus) and P1687 (no MIC bus).
The PCM is expensive. I was quoted $700.00 for a new one, not counting labor. The PCM has to be programmed to your vehicle but, this doesn't have to be done by the dealer like they want you to think. I found a company out of FL that sells refurbished and programmed PCM's. Allcomputerresorces.com. My jeep has been running fine since I replaced it a month ago. It was very easy to replace.
