I believe I had a failure similar to what you are experiencing. The car would start and run for a few minutes then die. I couldn't get it restarted immediately. If I waited until the next day it would restart then the same thing would happen. I initially thought the fuel filter was plugging up or I had bad gas. Finally it started, died then I couldn't get it restarted at all. I had it towed to a shop that works with restorations and special interest cars. They diagnosed a failed MSD box. A new box was installed and now the car starts and runs fine. HERE IS THE KICKER - I SENT THE BOX TO MSD FOR REPAIR. THEY CHECKED IT TOLD ME THERE IS NOTHING WRONG WITH IT. I will try the old MSD box again on the car in the spring when I am home again.
