Matters have gone from bad to worse. I barely made it around the block - the engine died three times! The first time it took quite a long time to fire up - probably 10 seconds - which seems like an eternity when I was blocking an intersection. The second time it restarted quickly and the third time it took a few seconds. Each time the engine died my foot was on the gas pedal although I was going at low speed in our neighborhood. The engine just died - lost power completely. As I said previously, the lights, horn, radio and other electrical items continue to operate.

I'm going to try to duplicate the situation in my garage. I'm plan to pull/push/tug on every connector and wire I can get my hands on to see if I can make it "die" in a repeatable fashion.

I purchased an AC Delco ECM but I'm not going to install that yet. Once it's opened I cannot return it for full value so I'll wait to see where my troubleshooting ideas take me.

Any ideas and constructive comments are welcome.
