ICE stalls on vehicle start after 3 days inactivity (P3191)

Very common problem. There are many threads on this forum related to vibration after shutting down while ICE is still in warmup mode then allowing the engine to cold soak. No known solution but as far as anyone knows no permanent damage is caused by the shaking.

 

The best practice is this: If you have the engine start (while maneuvering around the driveway or something) let it run for a minute before shutting it down.
I had a BMW that would refuse to start (act flooded) if I'd run it for 10-15 seconds from a cold start then shut it down to park. Once I learned to run it for a minute I owned the car for another 15 years without a repeat incident.

 

Alternatively select EV to move it. I had a 95 Ford Mondeo (US Contour) that did the same as your BMW.

 

With what you described I would suspect there could be a few things going on but I would start getting it checked at a auto shop and ask them to check both the sensor or injector but cold stalling problems or at least the one`s our car has experienced in the past have always almost been related to fuel problems.
