Surface Pro keeps going to sleep every 1-2 minutes of being idle

I am also having the same issue.  I chatted with MS and got the typical answer...I would need to do a complete reset of the machine which is not a viable solution.

After the May Patch-Tuesday updates, the problem seems to have become random lately. Sometimes, when I wake my Surface Pro from sleep, it behaves as expected; obeys the power plan I have configured. Other times, the bug takes over and puts it to bed after 2-3 minutes regardless of the power plan settings.

Creating a new user Account had no effect; after a fresh restart then sleep cycle, it still randomly went to sleep after 2-3 minutes.

Checked the Local Security Policy: Local Policies > Security Options > Interactive Logon: Machine Inactivity Limit and it was set to "Not Defined".

Attempted resetting the group policies again (although it didn't work the first time I tried it when you suggested it on CrashCtrl) using the Visual Basic Script on sevenforums.com. Performed a sleep cycle and it seems to be staying awake so far...though can't guarantee if it was just a coincidence that it chose to obey the plans this time in the random cycle.

Will update this post if it continues to obey the power plan for next week...

---EDIT---

As I thought, the obedience was just temporary, it has began going to sleep every 2-3 minutes again :| Any other thoughtful suggestions on fixing this problem?

Could Outlook 2013 be causing the problem? I'm using Outlook 2013 with 6 IMAP/SMTP accounts and 1 Exchange ActiveSync account (a Hotmail account). I have my old Laptop configured similarly, but with Outlook 2010 and Hotmail Connector instead, and none of this was ever experienced on the Laptop.

--EDIT---

Doesn't appear to be Outlook causing it. Restarted the Surface Pro, never opened Outlook, and it was obeying the powerplan. Then, after 2 screen turn offs (power plan is configured to turn off screen after 20 minutes), not sleep cycle, it then began going to sleep after 2-3 minutes :|

Might just have to dump the factory image of the Surface Pro and start from fresh, cause these nonsense bugs it contains are just getting more and more frustrating.

it was not the screensaver for me.  It was off completely.  the only thing that helped was windows full restore.

In most cases, it has definitely not been the screensaver. It certainly can be in some cases but in my case and numerous others, it was a security policy being enforced.
