Karl - Although it could be any of a number of things, have you replaced
your fuel filters? Another thing to look at that once gave me problems is
the grounding block for the points. It's under the plate that the points
mount on inside the distributor. Mine had corrosion and caused my engine to
mysteriously quit at random times.
