There has been a continual up and down over the last couple years with regard to the reboot issue.
If you try a google, there is a back and forth breakage between the Kernel and u-boot. General summary seems to be related to the power for attached devices, e.g. SD-Card, USB, EMMC, so what you have attached also seems to impact whether you are impacted or not. Even just changing the speed of SD-Card has an impact.
For any of the Libreelec team, the following might be of some help if you hadn't already seen:
