Sounds like either a fuel problem or the injectors need cleaning or replacements

The ECM is cutting boost (air) due to "overboost" detection. Once you turn it off and back on, things are find until the ECM detects too much
boost again.

This is a common problem due to carbon build-up in a couple of places.

I am no longer getting emails telling me that someone has replied to a topic. You will have to rely on the experts then.
