Possible, but not likely. I did have this happen with a heavy cleaning dose (ten bottles in 150gallons of diesel) of fuel system cleaner in an older diesel coach so I do say it's possible if there was enough crap in the tank.

Sounds like you're on your way to checking fuel volume/flow and perhaps a new filter, but you already know the exhaust is bad so a good place to start.
