I would not assume that, but you would know better than I.
Thr pcm disables the boost when:
When reverse gear is selected
When the vehicle is decelerating
When the engine coolant temperature is excessively high
When drivetrain abuse is detected.
If not codes are shown I would want to verify the coolant temp sensor is reading correct based on the symptom you have. If the coolant temp is excessively high then there may be the source.
