you may have a sensor on its way out, or some other electrical problem simply because it changes when you shut it off then restart it. take it to have the data read by a diagnostic computer. there can be codes or failures that wont set off an engine light

Your engine is overboosting and the ECM (Engine Computer) reduces the amount of fuel that is injected to prevent further overboosting.

The Vanes in the Turbo are probably stuck and need to be freed-up.
