At cruising speed of about 60MPH, when I suddenly accelerate (punch it, to down shift the auto-trans) the engine will suddenly turn off and all my instrument panel indicators would light up like a Christmas tree. When this happens I shift to neutral, turn off the ignition and restart the engine and it all starts working properly again. I wonder if I have some kind of electrical problem where the sudden jolt of the engine is knocking something loose.

Do you have any check engine codes? Does this electrical issue happen at any other time or do your headlights dim somewhat when you apply the brake pedal at night?
I never checked the engine code, but I will the next time it happens. Only happens the way I stated. I don't know about the headlight diming when braking. Something I'll also check the next time it happens.
