2019 FFH SE Dies Suddenly

Had my FFH a little over a month now. Over the past week to 10 days or so, it has died suddenly 3 times. I was able to restart after a minute or two. The first time I had just gotten to work and pulled into my parking space, and it died. Don't remember if I had shifted into park or not, but everything seemed to shut down instantly and there was some kind of message on the dash like, "Accessory Power Available" (can't remember the exact wording). Second time I was merging onto I-65 and was just starting to brake due to an 18-wheeler being in my way on the left. It was 4:30 am and dark. The headlights went off, engine went off, brake & steering assists went off, and there was no response from my pressing the accelerator. Saw that same message on the dash. Was barely able to steer over onto the shoulder and stop before reaching a bridge. Went through the motions of shutting the car off (not sure if it already was), waited a minute, restarted and everything was fine. Driving out of a parking lot yesterday and same thing, same message on dash. Shut off (I think, again if not already off), waited a moment and restarted, all was well. Wondering if others here have experienced this and if anyone has clues on likely culprits, ways I can check, etc. TIA
