What are you doing or what is happening when the sensor disconnects? Both the possible causes and the symptoms could be telling, so please describe such a scenario in as much detail as you can.

Just following using PD algorithm until a third sensor sees a certain color, but the problem is with sensors that are following the line. They sometimes just disconnect in the middle of the line following. I hope that helps describing the scenario.

It does help a little, at least we now know that the sensor is built in a model, which itself is moving. This means an intermittent contact issue in the cable is not excluded yet, so I'd suggest setting up the model in a way that eliminates all movements and check if the sensor still disconnects even in the absence of movement.

My EV3 color sensors disconnect a fair number of times. What can I do to prevent this from happening apart from changing the sensors and cables?
