George,
I have been thinking about this today A LOT since reading your post.... When this whole mess started your car was sitting there running and had been running well. Then it just died! There was no huge puff of smoke, knocking or anything to indicate that you had a huge break. You have checked timing and are sure it is in time and didn't jump or break a chain, and now you are sure you are getting fuel, it HAS to be electrical. You also have checked the distributor now three ways from Sunday and have not found anything. You also indicated that it tried to start so I would rule out the condenser. I have seen many of these bad, but EVERY time I have seen one of these bad, it would not even TRY to start. However, they are cheap parts. Might be worth a swap. I would have to say now that maybe it is in the start / run circuit. I had a ram charger once that did this but it was electronic ignition. With the key in the START position, it would loose power to the coil but had power when the key was in the run position. So as you cranked it would just crank, crank, crank then as you started to let off on the key to quit cranking it would hit a time or two.... It was the ECU. Are you sure that you have power to everything while cranking?
