Answer#1. Removing the battery cable while running wrecks the voltage regulator, and should not turn off the engine, the injection system is pure mechanical.
Note:
The regulator mounts to the alternator with two Philip's screws = easy DIY, remember to disconnect the battery first.
#2. The engine shutoff valve on the injection pump is vacuum operated = a disconnected line, bad vacuum check valve at the vacuum pump, bad vacuum brake power booster or bad vacuum pump will cause your symptoms. please read through the following thread for diagnostic and DIY data.

#3. Transmission fluid can not be checked without the engine running, the dip stick is red/black on the passenger side near the bulkhead.
Note:
It is not possible for this vehicle to suck transmission fluid through the intake, it could draw it into the vacuum pump, and wreck the diaphragm.
