I would say your problem is electrical. Make sure the distributor cap is clean and has no cracks. The coil needs to be clean and not have any grease/dirt that holds moisture. Check for a cracked coil. Finally, check the plug wires to make sure they are in good condition and have no cracks.
It sounds like your spark plug high voltage is bleeding off somewhere. That's why it sounds like it is not running on all cylinders, because it's not.
