Random restarts. 950xl

To those experiencing a lot of reboots...

I started experiencing them a bit a couple weeks ago and then installed the latest update and didn't have them since. That was until I added a passcode and windows hello back on. Then they started again. I'm wondering if those who experience this(on any phones) are halving it happen mostly while these features are active? I'm disabling windows hello and leaving passcode to see if I notice a difference.

I have thought in the past it may have had something to do with SD card due to the fact that once in a while it will ask to check the card.
