1994 Intrepid dash lights not working, won't start

[abrisendine]

While driving my 1994 Intrepid (3.3, 256K miles), the dash began blinking while the gauges jumped with the lights, then went dead. Within a minute, the engine died. I have replaced the computer beneath the air cleaner with a salvage unit, checked the ground beneath the dash, and no change. The only lights working on the dash are the oil and door ajar lights. any suggestions?
