During starting the signal to the starter coil is split off to the DME. During running the signal from the speed sensor (the one that is over the starter ring teeth) keeps the fuel pump running.

The spark is from the reference sensor -- "sees" a pin on the flywheel in front of the starter ring.

Possibly a bad connection at the sensors or the sensor tip has metalic crud or it's adjustment has drifted. A bad connection can be the connector does not latch properly to the other or even a cracked connector that has broken the inside wiring.
