What are you using windows 10 home or windows 10 pro or?
It sounds like a corrupt ACPI issue, I have a similiar issue with my laptop running windows 10 pro thanks to a forced driver update via Windows update. I was able to fix that somewhat using a windows 7 drivers for the ACPI controller - But still have a random shut down issue.
Have a look under the windows update history and check if any drivers were installed.
