AJM 1.9 PD: Intermittent Power Loss Troubleshooting

Hi.

'I've been experiencing occasional power loss issues with my A4, which has the AJM engine.'

It usually happens when accelerating from the 3rd gear onwards, around 3800-4000 RPM. After that, there is no power output.
When I then turn off the ignition and turn it back on, everything is normal again, and the full power is restored!
There are no error codes stored in the control unit!

Does anyone have any ideas?
I would rather not have to exchange various parts.

Thank you.

Yes, I have an idea...
