cscottyr, I had to do some intense troubleshooting on my 94 SSEi, but due to slightly different reasons. Only because on mine, the volt light would come on shortly before It started dieing. The way I started diagnosing was I purchased an ACTRON scantool and hooked it up, and drove around, days on end (and not too far from my home). The obvious symptom I found was the volts would slowly start decreasing (on the scantool "battery" catagory) from 14.3 at startup, to 9 volts then it would die. My GM service manuals for the car stated the PCM will power down at 9 volts. Long story short, this was with a new battery and a new replacement alternator (105 amp,...not good enough for these cars). My problem ended up being tarnished "power" connectors damn near everywhere, Power Distribution under the hood, fuse blocks, and main connector under the dash on the drivers side. One of them fixed it, just dont know exactly which? Didnt hurt to clean all of them though. When I get a chance this weekend, I'll look and see what the service manuals recommend for your problem (sorry, but tight schedule). Good luck.
