New to me. Sounds to me like the FEM (front electronics module) has failed. Take it to a Lincoln dealer.

Is he CEL on? You may be able to pull some diag codes from the pcm if so. Electrical/network problems are the hardest problems to solve and the best recommendation I can make is that you take it to a AAA approved FLM repair shop and pay by CC.

If you can pull DTCs from the PCM we might be able to provide better insight but at this level it is too difficult to say.

all the best to you and your LS.
