2006 Columbia Freight liner will start yet will shut off , engine will not stay
running . the check engine and the engine protect comes on then soon the
engine will shut off .
I suspect your engine management computer has detected something out of whack and continuing to run the engine may ruin it. I would check the oil and coolant levels. See if that diesel's catalytic is overdue to be serviced. The "five minutes idle to shut down" timer might be wrong. Turn on the cruise control and set it while idling. Just guessing. Get dealer to scan for codes. I was lucky to retire before all these computerized trucks hit the road.
