I recently started experiencing random shutdowns similar the the ones other folks have described here (opening the laptop from sleep to find it shutdown, shutting down randomly even when on wall power, etc.).
Before finding this thread, I tried a bunch of other troubleshooting steps (testing w/ different SSD, different battery, re-installing OS, etc.), and nothing seemed to work.
After following the advice here and removing the ethernet network preference thing and changing the .kext to .BAK, I was super happy to find everything working as normal.
Unfortunately, after about a week of no shutdowns, I had another random shutdown. I check the network preferences, and somehow the thunderbolt ethernet preference had reappeared. Does anyone know why/how this would have happened (no software updates in that period, automatic update off)?
Anyways, I was hopeful that that was the issue, but deleting it did not solve the issue. I checked the extensions, and all the .kext were still renamed to .BAK.
I bought the NoCrashMBP app that other people have had success with, but that also did not do the trick, and my machine is shutting down very frequently.
Unfortunately seems like I’m running out of things to try - has anyone else had a similar issue with reoccurrence of this problem? Was anyone able to solve it?

A bit of extra information that may or may not be helpful - if I check for previous shutdown cause, the code is always either -60 (bad master directory) or -74 (battery temperature exceeds limits). This was also the case when I initially had the problem, and since changing the .kext fixed it, I don’t think these shutdown codes are accurate, since it shuts down even when things are very cold and battery temp is room temp (per temp monitor). I suppose it’s possible I had two problems show up at once (thunderbolt bug and battery problem), although that seems unlikely since I also tested with another battery and the problem persisted.
I am running Mojave 10.14.6 on a mid-2012 rMBP.

'''UPDATE:'''

Turns out my issue was actually the CPU overheating - after replacing the thermal paste (and heat sink since I had to cut it away because all of the screws holding it in stripped out..), I haven’t had a shutdown in 5 days!

If you’re looking at this thread and none of this is working, I’d encourage you to check your CPU temps and if they’re high think about replacing the thermal paste. I think the only difference in symptoms (and I wish I’d paid more attention to this initially and realized my problem might be different) is that the fans did not spin up after the computer died as others here are mentioning. The machine just shut off and went silent/dark instantly. Other than that very similar to what others are describing, so a bit tricky to identify the problem.
