Ed, is this thing a speed density set up, or does it have a MAF sensor?

What are you using for a distributor?

I want to go back over some of this, and see what you've replaced, or bypassed.

MSD box?
Coil?
Batteries?
Crank trigger pick up?
Coil wire?
ECU?
Transbrake switch?
Master switch
Ignition switch?
Transbrake solenoid?
Starter solenoid?
Battery cables?

Anything else?

Have you tried looking over all of the wiring, and using wire ties or "strain relief" to keep the wires from moving anywhere?

Have you tried tapping sharply on your electrical devices? I'm sure you're familiar with the old "tap test" that we all used to use checking things like the MAF years ago.

Also, what was changed, or what happened, immediately prior to this problem rearing its ugly little head?
