I also have an 03 chevy silverado with a similar and had the same problem and got it fixed. The problem from what I understood is there is a carbon buildup around the air intake and doesnt allow it to "breath" properly. Mine would flutter but if I went around corners the engine would die from the load of the power steering and no gas. It would be ok if I went around the corner with my foot slightly on the gas. You could probably do it yourself and not have the dealer do it.
