My truck is loosing power in seconds , after 3-4 seconds the power is returning. That happens as many times as it wants, anytime, anywhere. When is loosing the power the check engine is not on. A second after loosing the power the radiator fan starts for 10-15 seconds. Sometimes the check engine is on and it shows SPN 108 BAROMETRIC PRESSURE 13 . I did 2 diagnoses at Freightliner dealership and is not showing any active faults and the mechanics don't know where from to start the repairs. Thanks and hopefully someone will help me. The truck is Freightliner Cascadia 2012 DD15 DEF
Cascadia 2012 loses power
