It could be the Hall sensor in the distributer or the ignition power stage, I have had both faults, and the car was acting like yours.
Look at the rpm-meter when trying to start, if it is showing 500 - 600 rpm, the ignition system is OK. If the rpm-meter is showing 0 rpm, ignition is dead and it could be a good idea to change the Hall sensor. It is always good to have a look at the rpm-meter when it's not starting, the rpm-meter is connected straigt to the ignition coil, low voltage side.
When my Hall sensor was broken, I found something very odd. I loosened the electric plug from the ignition power stage (with ignition off) and put the plug back again. The car started after that and worked sometimes for several days.
