Welcome to GH!
Sounds like a stuck wastegate (or bad wastegate solenoid)... that is forcing you into overboost. When this happens the ECU jumps in... flashes the check engine light and limits rpms to 4800. Turning ski off then on will reset until it happens again. Check the wastegate on the turbo that it can be moved (about an inch or so) and that it snaps shut (spring loaded). If the wastegate isn't seized and moves freely... then it could be the solenoid that the ECU uses to control the actuator for the wastegate.
