We are working ont the following problem. Any assistance will be
appreciated.

I have experienced 4 times on my TSI0550E (1) B a partial power failure that
last no more than 7 seconds.

All times in cruise over 7,000 at 31 inches 2400 rpm. The sudden failure
drops MA to 23, RPM stays the same. Power is restore  on its own without
additional failure.

This engine is a twin turbo, twin intercooler.
