What causes engine bogging and loss of power in '04 Nissan Quest w/no warning? on 2004 Nissan Quest

Cannot get RPM's over 1500 after car warms up. No warning lights on, engine gets louder and sounds like low growling.

What are the trouble codes. Get it scanned with a professional scanner not just a generic code reader.
It is not ease to diagnos a "modern"vehicle if there is no Check engine light on and that full of all kind of sensors.
But by the symptoms i would think a clogging catalytic converter that blowing back fumes to engine.
But i am just guessing. That would be best to take it to a professionl shop.
