Only a guess from this side but, a stuck turbo would do all of that. And it take mostly time to do this repair!! That 03 should really sing! Test,verify,repair.

Check for fault codes first. Check fuel and air filters, this is often overlooked. Check for any intake intercooler hose or boots leaking. Like mentioned, the turbo vanes stuck or an exhaust restriction can cause low power too. Did this come about suddenly or slowly over time?
