For your privacy and security, I have covered the personal information included in your post. Please avoid sharing any personal or sensitive information publicly, such as serial numbers, order details, email addresses, phone numbers, or case-related information.
I understand how frustrating it must be to have the random restart issue return after you have already contacted support.
Since you already have a support case, please contact Microsoft Support again and provide the previous case number to the new support agent. The agent should be able to review the case history, see what troubleshooting or service was previously provided, and advise on the appropriate next step under the device’s warranty.
When contacting support, explain that the random restarts have returned and mention any troubleshooting, repair, or replacement that was previously completed.
You can also open the Surface app, go to Help & support, install any available updates, and run the available repair or diagnostic tool. If the issue happens again, note the approximate time and whether an error or blue screen appears, as this information may help Surface Support investigate it.
Please keep in mind that this is a public user-to-user forum, so community members cannot access or update support cases or warranty records. For privacy, avoid posting the case number, device serial number, or account details publicly.
