    Hello, driving a 2015 freightliner m2 106 26ft box on I 70 taking a load to Washington, when all of a sudden speed starts declining. No engine lights indicators and drives fine for a few minutes then starts back declining when at the 55- 65 mark...after few seconds I'm able to resume speed. Any idea of what is going on?

    I do not know about your M2. In the old days we would pull over, jack the cab up and spin a new fuel filter on it.
    Call you read any flash codes?
