In the past month or so I've started encountering random no-starts with my 2011 GTI CCTA.
I first encountered this when under acceleration on an on-ramp when it stalled but started right back up once I pulled over.
The second time was after leaving a parking lot, it stalled and refused to start until I waited.
If the car is cold, it starts without issue. If it is warm, it will sometimes have a delayed start or once the engine turns over, it will idle rough for a few seconds before stalling. The only option is to wait an hr or so which seems to be enough time for the car to cool and it starts normally. There is no power loss or any other symptoms when the car is running.
So far I've replaced the fuel filter and have not been able to borrow a VAG Com to scan it. I'm going to try and do that this week but wanted to see if yall had any ideas?
I ran into something similar with my MKIV TDI when the fuel pump died but it wasnt intermittent like this. From what I've read on forums it could be the Low Pressure Fuel Pump, High Pressure Fuel Pump, Coil Packs, or Spark Plugs.
Here is a video I took the last time it wouldnt start.

Edit:
Forgot to mention that the car is stock.
