I was a mechanic my entire life. When it dies and won't start, I'd pull the air cleaner and see if its squirting fuel into the engine, if it does, it's not a fuel problem. If you want, you could also spay some starting fluid into the carb and see if it starts. If it still doesn't want to start than its probably the ignition. Next, I would check for voltage to the coil and if it's good, I would try a coil since you already replaced the distributor. When you check for the "available" voltage at the coil you need to remove the wire you are checking voltage at or make "sure" the points are open, otherwise if they are closed the circuit is complete and you will be doing a "voltage drop test" and get a zero reading or a slight voltage reading instead of the actual available volage to the coil. Even if the coil does not fix the problem, you'll have a spare coil. It's always a good idea to carry a spare distributer and coil with you on an old Ford and the tools to replace them.
