The nice thing about intermittent failures is that if you wait long enough they stop being intermittent. Then they are easy to diagnose.
Working on cars and trucks is not my favorite thing but the blue truck told me it did not want to move from the driveway. Fortunately, it was resting in the shade of a large tree.
A new ignition coil, rotor and distributor cap later and it moves down the road.

|There are two holes at the 9 o'clock position and two more at the 3 o'clock position. The inner holes are locating pins and the outer holes are screw holes. The first replacement part did not have the pins offset.
Working on cars was a lot easier before I needed bifocals and when I weighed 130 pounds and was as agile as a squirrel.
