Fairly certain it's not the crank sensor.
I was trying to think about things that I've done that resulted in like symptoms. The first would be an unplugged (non-functioning?) AFM. You may have been on the right track replacing the ignition switch. Have you looked at the ETM and checked the other components and connections in that circuit?
Do your cluster warning lamps remain on when it dies?

The warning lights do come on when the car dies. I have a few extra eta ecus so i tried one a few days ago when this happened, no change. I also have a brand new main relay for troubleshooting purposes and i tried that with no change. I exchanged the unloader relays with the headlight relays with no change. I have unplugged and tried to run each of these sensors with no change afm, tps, baro sensor, o2 sensor, cold start injector, idle air control valve.1989 325i Alpine s52 coupe

It seems like it is losing spark right after starting. Does anybody know what the second sensor on the bell housing actually does?
