16inch MacbookPro randomly disconnects from power

If you region has open Apple stores at the moment, what I would recommend is this:

Back up your data and take it to an Apple store. Ask them to try another charger. If that doesn't work, ask them to reset the T2 Chip with Apple Configurator. If the problem persists, you probably have a faulty machine.

1. My Macbook Pro keeps randomly disconnecting from charging which is really annoying as it loses power really quickly, I'm not sure why. I've had this for not even a year and this issue is really frustrating. Also, I am using the 96W power brick and original apple cable as well. I keep getting a "thunderbolt power on failed" error as well which happens after it randomly restarts itself as well. As to steps I've taken, I've:

tried all ports

2. Reset SMC

3. Reset NVRAM

try turning off the Battery Health Management as a test.
