Phillippe:

Jim is correct - it’s one or the other.  If you are seeing no power on #4 to the distributor, I would suspect an over-heating/failing coil.  If you are simply seeing no pulse … then the Hall sensor/sender would be suspect.   I’ve had a coil fail with similar behaviour to what you are experiencing - when it became too hot.   Thus far my hall sensor is fine - though I’ve been told they fail more frequently than coils.
