Most likely one of the speed sensors in the transfer case is bad. The Control Trac measures rear driveshaft speed and compares it to the front to determine the dwell time of the clutch pack in the transfer case which results in the amount of power being sent to the front wheels. If a sensor is bad and either the front appears to be going faster than the rear or the front isn't registering with full lock on the clutch, it will flash the 4wd lights to let you know there is a problem and just disengage. The Hall-effect sensors rear the passing gears of a "tone wheel", so you can check to make sure the connections are tight and that they don't have a lot of gunk built up on them (metal bits stuck to the sensor will make it unusable), or just replace both...they aren't terribly expensive.
Another failure mode for 95-96's is that the vacuum line that allows disengaging the front wheels from the differential can get separated, so you just can't get out of 2wd. That was dropped in 97 and later as they always have some sort of 4wd available.
