You are not in power reduction mode. If you were one of the lights would be on.
I would recheck fuel pressure, hi and low. Both at the 3 times I posted.

What prop pitch are you running? Excessive pitch will lower the top RPM but you're at the minimum of the RPM range now but still in spec. Do you know how to properly trim up the drive once you're on plane to achieve max speed and RPM? I ask these questions as you may have NO problem at all and are just throwing money and parts at something that isn't broken to start with.

Or your fuel vent is clogged, which would explain the duration of time (the 1 to 1.5 hours you mention)

Thank you so much . One more question do you think there is a filter in the file line in side the tank could be clogged ? I know there is fuel filter at the fuel pump and it’s changeable but my concern now if there is fuel filter at the end of the line inside the tank could be clogged and making this issue? If yes is there a way to get to it ?

There are many things the can cause a fuel delivery issue. This is why the first step is to test fuel pressure.
