Complete engine shut down when driving car at slow or highway speeds. Loose all power. All gauges go dead. Let it sit for ~ 10 min. and starts up again: Have replaced the following: C1 Wiring Harness to computer (all terminals), have replaced fuel filter, crank shaft pos. sensor, ignition switch, ignition lock cyl. No 'check engine light' ever comes on. Grounding ok.

Question: do U think I need to replace main computer? thanks Gil

Will it crank now? Stop tossing parts as you are just pleasing the parts outlets. A code reading would help.

If it won't crank then that's another issue,
