It does sound like fuel cut do you have a aftermarket boost gauge or boost controller on the car?

Do an error code check to confirm what the fault is.

On a 185, once boost cut has happened you need to reset the ECU otherwise it runs a safe mode and boost cut triggers at a much lower level.

On a 205, boost cut automatically resets and normal operation re-commences after a few seconds.

could also be knock sensor fault, this triggers at 3K RPM but just retards ignition and limits boost doesn't cut completely.
