If you suspect or straight up know the ignition coil hasn't been replaced in the last 10 years I would go ahead and replace it anyway. They break down after 10 years and cause loss of spark and engine power which will be especially noticeable from midrange rpm onwards. A quick test - next time it dies try to pull a spark plug and ground it onto the engine while someone cranks it to see what or if a spark is present. Not super realistic to pull off as it takes a few minutes to do this, unless you're already anticipating a glitch and intentionally set if off. My money is on an ignition fault on this one. Fingers crossed you get a win and solve it
That's a great idea geezer; I just thought, keep a spare spark plug handy or a sprak plug tester plug; no need to pull the plug just the wire... Could even have a spare wire on hand and connect it to the distributor cap (less heat & grease + easier access) I love the way you troubleshoot dude, tortron is smart too... Must be that southern hemisphere air, it clears the mind ?
