Subaru BRZ with Proximity Key Fails to Start

For the second time now my Subaru BRZ failed to start upon command. The ECU seems to boot up and do everything normally, EXCEPT actually engaging the starter motor.

The first time I was in a dark gravel parking lot and eventually had to resort to pulling the ECU-B fuse (presumably the ECU ignition-off-draw fuse) and putting it back in to reboot the ECU. (mind you that was about the 7th fuse I pulled)

Both times it has happened I was in a hurry to get the car started ASAP as I was leaving parking areas and wanted to drive my shiny new car past my co-workers/friends to show it to them as they also were leaving.

I am wondering if I have run into a "race" condition bug in the engine ECU where I provide control input (i.e. start signal) too soon while it is in the process of booting up still, and I get it into a "wedged" state.

This second time I decided to video tape my troubleshooting procedure so that I can help the dealership/Subaru troubleshoot. See the video below:

Anyone else run into this kind of issue?

Gotta love software!

P.S. I absolutely love the car so I am not really unhappy in any way. I am pretty technically/mechanically adept, so no big deal so far. I do hate the stereo though and the Bluetooth is utterly useless. Also, I have noticed the passenger side window is not doing "auto-down" very well today perhaps due to the humidity. I have to press the button harder, or multiple times. Not sure if it is a switch issue, or if the force limiter is causing the "auto" down feature to kick off since there is too much friction.
