no alternator charge very weird

Autopage RS-860 in a 1991 Jeep Cherokee. Again, working flawlessly until today. Remote started it as I was walking towards it and as I got to it, the Jeep just stalled out. I got in and manually started it with the key and drove it home. No problems. As I sat in it at my home, I remote started it and then removed the key. Thats when I noticed my voltage gauge go to 9 volts and then the Jeep stalled out. So I started it with the key and the gauge read right around 13.5 volts. Remote started it again, saw the gauge drop to 9 and inserted the key and turned it to on. Gauge went right back up where it belonged. Very weird. I checked the fuses and nothing is blown. Double checked the wiring and nothing has come loose. Why would this happen? Remote start issue? Jeep issue? Anyone else run into this problem?

Now that I think about it - I lost the Ignition output on the brain didn't I?
