    Sounds like a faulty roller switch, located under the feedboard. It is common after years of use that the mechanical parts wear out, doesn't usually involve the electrical contacts, but those should be checked. Loose wires in the counter terminal strip. Check all blue wires in electrical cabinet. These are your 24V DC conductors.

    I have checked all blue wires. It has been perfect.

    Great, but I hope you are focusing your attention on the roller switch. I have replaced many of those switches over the years because of the issues you've seen.
