hi all, we had a client who had this exact issue that most on here are dealing with,
 
not sure it'll be the answer for all of you, but after searching for about a day, this solution that someone gracefully shared on https://apple.stackexchange.com/questions/306714/macbook-pro-15-retina-mid-2014-random-shutdowns seems to have solved our issue.
 
just a note: the solution seems to modify a thunderbolt file, some mention that external thunderbolt displays will sometimes require a reboot to work, however it beats having to pay $400+ for apple to service your laptop.
 
=== Update (05/14/2020) ===
'''''Thanks Mike Sims,''' i can't take any credit.''
 
''just helping lead others to answers others have gracefully shared, and get a little more life out of these Macs.''
 
''that being said'':
 
'''New update:'''
 
''as of the MacOS 10.15.4 Update the fix above stops working. however,''
 
credit:OlivierFelix for the continued fix:
 
https://www.reddit.com/r/MacOSBeta/comments/c6f6e7/catalina_random_shutdown_applethunderboltnhikext/fb8zw0w?utm_source=share&utm_medium=web2x
 
In summary this is what i did to get the mac back up and running:
 
'''Reboot into recovery mode holding down CMD+R after boot chime, then open Terminal.'''
 
[code]
csrutil disable
[/code]
'''Reboot normally - open Terminal'''
 
[code]
(If you have Catalina): sudo mount -uw / ←don’t forget the forward slash
[/code]
[code]
sudo cd /System/Library/Extensions
sudo mv AppleThunderboltNHI.kext AppleThunderboltNHI.kext.BAK
[/code]
('''New as of10.15.4''') in addition to the NHI move performed above now add the step below as well:
 
[code]
sudo cd /System/Library/Extensions
sudo mv IOThunderboltFamily.kext IOThunderboltFamily.kext.BAK
[/code]
'''Reboot again into recovery mode and open Terminal'''
 
[code]
csrutil enable
[/code]
reboot normally.
