1998 Grand Caravan Oxygen Sensor Failure

Have a 98 GC Sport 3.8 and the oxygen sensor is being reported bad for the third time. Have replaced the O2 sensor at the Cat twice now, but am still seeing the service engine light. Anyone have experience with this problem, or have any ideas what could cause the service light to come back?
