Looks like I spoke too soon. Both PB's reset themselves overnight, running Stretch 9.3 IoT. With the Stretch 9.3 IoT release, it is more like once per day, than the previous four times per day, but it is still happening. Happens on both 4.4 and 4.9.
To answer Robert's question. I generally don't touch the kernel on any of my installs, so whatever comes on the image. bone-debian-9.2-iot-armhf-2017-10-10-4gb.img Linux beaglebone 4.4.91-ti-r133 #1 SMP Tue Oct 10 05:18:08 UTC 2017 armv7l GNU/Linux When running from Vin, reboots three or four times (randomly) per day.
