May I suggest a couple of diagnostic items?

Electrical:

1. Until you isolate the problem, strip the unknowns. Remove the MSD box, the strange or funny ignition items and anything else that may inhibit the firign of the spark plug.

2. Make the ignition system as basic as possible. Then run the car and see if it does anything like what it was doing.

Fuel:

1. Remove any questionable situations from the fuel delivery system. If you are drawinf fuel over a hump, up hill or over a long distance, fix those to gravity feed until you find the problem.

2. Strip all of the unusual things from the fuel system. If you have three filters and one is so small it might be stopping fuel flow, bypass it.

3. Install an inline fuel pressure gage and monitor the fuel pressure at the carb. Run the car and see if it does what is did before.

I messed with this same type of problem for a year and was so frustrated, I wanted to hire someone else to fix the problem. Finally, I did a system by system check and found an assortment of things that made the car die.

Once the car is running and you can take it out without incident, add ONE and I mean ONE item at a time until you determine what is the cause of the problem.

I ended up with a new location for a fuel pump and a new pump itself. two new fuel filters and I tossed the ignition assist box ( an old CD ignition system ). I also ended up with new wires and plugs.

Just my $0.02
