Mine turned out to be to hall sender in the dist.  Took the ecu with it.
Difficult to remove from dist but was shorted out on the bottom of the
plastic wiring connector elbow.  Would crank, catch (sometimes) & die.
Sometimes would run until you tried to increase the engine speed.

Easy to check with a multimeter.

The old one had all of the bottom plastic missing and been glued on the
sides (Also only had one screw holding the unit in.)
