I am experiencing the same problem. Brand new 15" Mac Book Pro 2018 (32G, 2.2, 512G), purchased 4 weeks ago, as of the past week, it has frozen twice. The mouse freezes and after 60seconds, it restarts.
No major load, temp is ~144, I clicked on refresh in chrome for a shopify website we work on daily.
I generally do not restart my computer and just close the lid. Uptime is a 7-10 days on average between reboots.
It does not generate a crash log as you can see below: Today's Date: Nov 12, 2018
