Hi Matthew,
First things first, here is the direct link to the App that you need to install from the Windows Store: https://www.microsoft.com/store/productId/9NMR79ZTJFTC. Just click on the link, it should open the Windows Store App direct at the right place, from
where you can download this Intel App.
Then maybe these screenshots help.
This is what the App looks like when it's installed and ready to launch (my computer in French...):

When you launch the App, click first on the left where I've put a "1", then click on the top of the screen on "Power". When done, you have to set the "Panel Self Refresh" to "Off" for both "On Battery" AND "Plugged In". When done, just reboot.

I was running crazy since weeks with my brand new Surface Pro 7 i5 / 8GB / 256GB stopping anytime abruptely. I applied the procedure described here above, and now this SF Pro 7 works like a charm :).
Hope you'll enjoy the same result...
Cheers
