Transponder acting strange

Has anyone had this issue? WHile traveling thru Class "C" airspace, I got a call from the controller asking me to cycle my (Bendix King) transponder. The controller was getting erratic altitude reading from it. Squawking 1200 it works fine, but acts erratic with discreet codes. Before I take it to the avonics shops I figured I would ask the forum.
