In your videos the starter and battery sound fine. If you watch the tachometer needle it gives a pretty good clue that you're either losing power to the coil and distributor or the ignition module is going bad. The needle does not budge when the engine is not starting, it should be showing the engine's RPM while trying to start. You can test the first possibility, loss of power to the ignition system, by watching a meter attached to the positive lead of the coil with the key on and when you try to start. Voltage should be maintained above about 10 volts. If you don't have power there then focus on that. It would be worthwhile to clean the connections to the coil and ignition module and see if things improve. The old E12-80 and E12-92 modules are known to go bad eventually though. Wouldn't be a surprise if that was the problem, although they usually fail when they get hot. p.s. the magnet under the stator ring is known to break on those distributors also. That might cause a low trigger pulse to the module at starting RPM. That kind of fits your symptoms. It's not obvious, you have to remove the breaker plate and lift the stator ring to see it. Also, one reason the magnet breaks is because the shaft bushings on those distributors wear out allowing the 6 pointed reluctor wheel to contact the stator ring. Here is a good resource showing some of those things. The result of a worn out bushing is shown way down at the bottom. http://www.atlanticz.ca/zclub/techtips/distributorrebuild/index.html
