    Heck, those hard to find (as in expensive) coils look to be in good shape. No leaks or visible cracks on them. I’d check these ones first with an ohmmeter and also clean and polish the points and all contact surfaces of the brass mounting pieces. Chances are the caps (condensers) are going south too and should be replaced. While you are in there, new spark plug wires might be needed to along with a fresh set of NGK plugs.

    As a motor warms up, the heat does funny things to the electrical components. The coils start to fail along with caps etc. A good ignition tuneup might solve your issues.
