What RPM / gear / conditions are you experiencing power loss?

Make sure the pump is actually running, it can be as simple as just a circuit breaker.

Good question - Happens at different times, different speeds. Will try manual upshift/downshift when power loss occurs and note RPM's.

Should this throw an error code? Will confirm with mechanic that pump is working.

No, IC pump related errors doesn't throw codes. Atleast it didn't for me.

IC pump was replaced - will re-check for leaks etc. Am sending ECU back to Renntech for re-flash.
