    It's about time for the distributor to give some trouble, this is a common problem. Remove cap and check for side to side movement of the shaft. Suggest replacement of the assembly with a 'new' unit! Can find a shop with a scope to test the ignition system if needed, that will tell the tale! Even some of the older oscilloscopes will work on this system! Can not beat a scope for pinpoint testing!!!
