With high mileage quite a few problems may be causing this, but the distributor has a pick-up plate that may cause this. Wiggle its wire and see, while running, or replace. But check the whole secondary plugs, wires, and cap and rotor also. The small little tabs that pass through the pick-up loosen up also. Round plate.
See if it has any engine codes with a scan tool(electronic). Or you can use the key to look at the flashing 'check engine' light in the dash. Ok
