Hello, I have not seen this issue but, I would think you have a poor connection or damaged wire in the circuit. It could be an ECM but, usually wires and connections are the more common problems.

Follow this guide below to see if you can locate the issue. If it is not helpful, you will need the dealer to connect CAT ET to view the fault codes and find the real problem.
