My mid-2015 MacBook Pro dies randomly

I don't remember 10.13.6 breaking anything that ran in 10.12.6, fwiw.

You may be right though on how long it'll keep going.

From the crash report, I'd say its the Graphic Card,not everything will run in Safe Mode, but try it & see if it ever crashes in Safe Mode...

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.

It generally requires a new logic board, only graphic cards would be used ones.

This Mac is of the generation that often had the discrete GPU chip fail.  

I have this model, and my chip has failed. I force my Mac to use ONLY the integrated intel GPU and that avoids the discrete GPU issues

gfxCardStatus is a free menu bar application that keeps track of which graphics card your MacBook Pro is using at any given time.

You can force a Macbook Pro to use the Integrated intel graphic via gfxCardStatus

nvram boot-args="-v"

reboot

See if we can get a report...

We need to see what all is running, a report from this will not display any personal info...

EtreCheck is a FREE simple little diagnostic tool to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac. It will not display any personal info.

Pastebin is a good place to paste the whole report if you capture the URL while there…

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck. In a Reply before you click post, look for this to add longer texts...
