    I have a 2012 Cascadia with a cummins engine and it turns off in on alot while its running.

    This happens randomly. I could run for 800-1000 miles with no problem and suddenly truck turns off for about 10 seconds while it is running and because the truck has speed it turns back on by itself. Because off the motion of the truck even though truck turns off, it will turn back on by itself without me having to touch the key switch.

    When the truck is cold it does this alot, maybe it turns off and then on about ten times continuously..

    I took it with freightliner about 3 times and also 3 times to cummins and as well to other truck shops and no one has been able to solve my problem.

    Just trying to see if someone could know what this is.

    I had a similar issue with the 2012 Cassie I was leasing, not as bad as what you describe though. No codes, nothing in the ECM at all registering a problem. It stopped doing it after I replaced a pair of batteries and cleaned all connections in the battery box so I'm thinking it was a loose wire connection.

    It sounds like it might be a power issue. I would try what Keith said and start and the batteries and work your way towards the ecm cleaning up and inspecting the connectors.

    Did the dealer happen to say if you had any inactive codes? Some mechanics will just write off inactive codes as not being the problem because they are inactive. But, with an intermittent problem like yours, the active and inactive status of the codes will change pretty quickly if the truck is "correcting" itself
