I can trick the car into a low power mode, followed by loud idle...

It seems as though I can trick the car into having no power on occasion. First time it just sort of happened... came to a stop at a stop sign and upon pulling away I had no power, regardless of how much pedal I gave it. I pulled over, car was running loud so I turned it off and sat for ~30 seconds and turned it back on. Car returned to normal.

Today I was slowing down and shifted into first, rev match and immediately lost power. Revs held at 3k, but they wouldn't go anywhere. It came back after stopping (in traffic) and then pulling away, but when I pulled into my parking spot, the car was idling very loudly...

After turning the car off and on, it's fine.

Noise Warning... this is just after I got home, which is ~1 minute after the incident. I focused on this one piece because of the amount of vibration being caused. At ~0:29 you can really see how rough it's running.

After turning the car off an on

Anyone run into something similar?

This might be the limp mode issue that everyone is talking about. I'm not sure though. I'd like to hear what others have to say.

Definetly a fan problem, it seems a bit out of sync and rotates slower

That's limp mode for sure. You may want to read up on "First F30 Limp mode" thread.
