Rich - I know that you've been bouncing this problem around for a while. I wanted to relate something that happened to me on an SOB (some other brand) several years ago. This was a Honda Accord. I had done a complete tune up, with all new parts. A week later, my wife was pulling out of a parking lot, and the car died. It wouldn't even sputter when attempting to start it. I pulled a spark plug, and it showed a fat blue spark when grounded to the engine while cranking. The carb has a fuel level sight for the bowl, and was at the proper level. The accelerator pump shot a good stream into the throat as it was supposed to do. Cam belt, distributor rotation, all things checked out okay. All the elements for "life", but it wouldn't run. In the final analysis, the new distributor cap had a casting flaw in it that was not visible to the naked eye when clean and new. After some period of time, traces of carbon collected in the flaw, and it eventually became an alternate electrical pathway for the HT spark. It turns out that the electrical resistance for the spark plug in the cylinder during the compression stroke goes way up. The spark looked for an easier path, and found the flaw to ground itself to. The spark plug worked fine when removed, because of the lower pressure and the lower resistance. All this to say ... could you have a flawed cap or rotor that is bleeding off spark when the pressures build in the cylinder suddenly during acceleration? It's a wild idea, but you've heard many so far in this little journey of yours.
