Dewalt orbital sander problems

Hey guys I have a DeWalt orbital sander DW 420, and it is not working properly. It sounds fine when you run it without applying it to any surface.  But, when I put it onto anyting under normal pressure the head of the sander begins to slow and eventually will sotp if I dont pick it off the surface.  The motor sounds fine, so I thought there might be a clutch or something in it, but after looking at some part list for the sander I decided it didnt have one.  I am stumped, so if anyone knows anything about this let me know.

    There is an RPM adjustment on the side.  It is set very low right now.

    I dont see any adjustment on this one.  It spins plenty fast until pressure is applied.  I can even hold it with my hand.  Kinda scary but I can do it.

    oops, sorry, bad info, mine is a 423, variable speed

    Sounds like it has to go back :(

    Haha! I had a friend give this one to me.  Maybe he knew something I didnt!  Given that fact though I think I will just have it fixed or do it myself if anyone has an idea of what wrong with it.

    Sure sounds like some kind of clutch  issue.
