Write out syslogs to disk or better yet mirror to grayling or something, there might be valuable information right before the reboot.
I've also had weirdness where the CPU/iGPU was just faulty and the IME would halt the system. That took weeks to diagnose.
Definitely reach out to support!
Could be heat or RAM related. Have you run a memtest on it recently? And how does the temperature look when it reboots?
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
