6.7 dies while towing
2018 6.7 gives a reduced engine speed while towing up hill with max boost. Engine just shuts down. No codes or check engine lights. Cranks right back up and goes again. Any ideas? New to forum.
Thanks

I doubt the problem is the fuel filters, but if you're towing, the fuel filter change interval isn't 30K, it's 15K.
How much are you towing? Pickup or chassis cab? What are the engine oil and coolant temperatures just before it shuts down?

I'm really interested to know the outcome of this since temps are very reasonable but seems temp related (more weight, more heat = faster shutdown). What does the analog temp gauge show prior to shutdown? Bad sensor somewhere is my guess. Does your dash report soot percentage?

Hooked up a reader and replicated shut off. Got a P0093, large fuel leak. No fuel leak existed. Once truck restarted, truck cleared code on its own. Replaced fuel regulator on the end of the rail. Will follow up after a few days of running.
