Engine dies while driving...

Hey everybody! First I'd like to thank everyone for posting their most helpful information on this forum. I've saved bookoo bucks doing things myself having learned how to do it here.
I've got a '92 Lsi that just started dying whenever and wherever it wants to. It'll die sitting at intersections, it'll die doing 75MPH on the Interestate, it'll die when it's cold, it'll die when it's at operating temperature, it dies at 10,000 ft altitude, it dies at 6,000 ft altitude, in short, there's no common denominator. I'm afraid that the engine controller computer is going bad. Does anyone else have any ideas? Thanks and God bless.
