Sounds like multiple different things going on at once that may be unrelated.

First, it sounds like the injection pump timing is off somehow. The cold start device was disengaged before timing the pump, right? If not that will result in actual timing that is much retarded from where you intended to set it.

Second, it sounds like a coincidental but separate failure may have happened with the starter, maybe a stuck solenoid or pinion gear, or a failed ignition switch, that caused the starter to remain engaged and energized for a long time while the engine was running. That would have burned up the starter, and also either the battery cable or alternator B+ wiring near the battery due to the extended high current draw from the starter motor and high charging current from the alt as it attempted to mitigate. It might be what caused the motor to stall also, if after a while the starter eventually drew the battery voltage down enough that there wasn't enough to keep the IP fuel cutoff solenoid open.

Did you hear a swishing or whirring sound while it did run, like the sound of the starter still being engaged in the flywheel? Was it willing to crank again right away after it stalled that last time, or did you have to recharge the battery first? Does it sound normal when cranking now and do the starter and ignition switch seem to be working normally? What happens to the voltage across the battery terminals when the starter is engaged now? And the voltage at the IP solenoid when cranking?
