My MacBook Pro, Late 2013 has been checked out at the local Genius Bar and all systems were green with no issues, yet my laptop still shuts down within minutes of startup?
How will this be fixed?

And did it shut down in front of the Genius Bar ...?
What did they check for, Hardware?
To trouble shoot further you can:
—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support
This will tell you if it a universal issue or isolated to your user/admin account.
—A SafeBoot How to use safe mode on your Mac - Apple Support will sort many anomalies
Takes a bit longer to get to the login screen, does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, font cache, etc., third party system modifications and system accelerations are disabled.
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
a reboot will put it back to normal mode.
This test will tell you if third party interference; most* extensions etc are not loaded in safe boot mode.
***if you have a wireless keyboard with rechargeable batteries connect the charging cable before booting to Safe Mode.
This will make it act as a wired keyboard and will result in a successful Safe Boot mode.
unplug all third party peripherals
Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus
