I have a 2005 fleetwood discoverey with a c7 cat that loses power under load and smokes black. It runs fine going down hill but soon as you start under load it falls on its face. It stays running just no power. If you let off for just a little bit it has full power again for about 3 sec then loses power again.

Do you have a boost gauge? My first instinct is a turbo issue. If it has a wastegate or vanes they may be sticking or having an issue with their actuator.
