2016 MBP, Everything Breaks Down Suddenly

Hello,

I have a the non-touchbar 2016 Macbook Pro, running macOS 10.12.6. Recently, my MacBook Pro just suddenly breaks down. Here's what I mean:

• The WiFi would stop working
  • My current connection would no longer work (webpages don't load, no longer connect to the internet)
  • I am unable to connect to a new connection
    • The WiFi icon keeps doing that pulsing animation that plays when it connects to a network, but it just keeps pulsing and never actually connects to any network
  • Sometimes, the WiFi icon would have an exclamation mark on it, and in Network Preferences, it says "No IP address" under the WiFi section.
• I am unable to quit out of applications, and have to Force Quit
  • For example, I would CMD+Q to quit out of Safari, but it remains active in my dock, with a black dot under it, and it says "application not responding" when I right click the icon. I have to open Activity Monitor, and force quit out of Safari to actually close the application.
    • This happens for most applications when my MBP just breaks down
• The volume buttons (F10-F12) don't work anymore
  • During this period when everything breaks down, hitting the volume buttons do nothing
    • No volume toast shows up on the screen, the volume doesn't change, etc.
• I am unable to restart/shut down, and have to force shutdown
  • Clicking Apple Logo -> Restart/Shut Down does nothing. It literally does nothing. I have to hold down the physical power button to actually shut down the computer.

That is just the stuff that I quickly noticed during this period of breakage. After I restart, and relog back in, everything is fine. Everything works normally and perfectly fine, for a few minutes. Then, suddenly, things break down and everything above happens again.

Does anyone know any resolution for this issue? Has this happened to anyone else before?
