I don't see the belt on your list... I would have replaced it first.

The answer's in your "mash the gas" comment. When you increase the speed things are moving at you decrease the belts ability to grip things well enough to keep'em moving. Your belt is past its prime so it can't hold past a certain point in the rpm range. Like the last guy, I say "Ditch the belt".
