I have an Arris sb8200 that keeps rebooting all day. It is actually really annoying. The cable comes from the ground at my house and goes into a weatherproof box. The cable screws in a ground block, then to a splitter, then through the wall where my modem sits on the other side. I already replaced the coax between the ground block and the splitter, and again from the splitter to the modem. It is still happening. I attached the log file. What do you think? https://ibb.co/fVgRnd1

Your signal strength is too high, which usually means your internet provider's equipment isn't sending the right message to your modem and thinks it needs more power. This often points to the wires between you and them being bad. Try plugging the modem straight into a ground block with a short cable to check if the reading goes down. You might find that there is water or dirt in one of the boxes outside where they connect, blocking the signal.
