MBP Shuts Down After Booting

MacBook Pro (15-inch, 2018)

Processor: 2.6 GHz 6-Core Intel Core i7

Memory: 16 GB 2400 MHz DDR4

Graphics: Intel UHD Graphics 630 1536 MB

Serial Number: C0***G5J

This MBP shuts down (the screen goes blank) immediately after I boot it. Often I leave it to sit for a few days, unused, and not plugged into the charger. Hit the power switch, boot up, log in and the screen goes black.

I assume the battery is completely drained, but yesterday when it happened I plugged in the battery charger and it came back to life. The battery indicated 57%.

What gives?

For a while, I just assumed the battery drained by itself while sitting there, unused, not plugged into the charger. Seems odd, though, that it would drain after a week or so.

System Information indicates the battery is fine.
