Same story I heard, emissions requirements. The 7.3 was hard to clean up. Ford rushed the 6.0 into service, and as a consequence the early ones had issues. 10 scariest words in the english language per Reagan? "I'm from the federal government and I'm here to help."
Also I think Ford wanted their own diesel, and Navistars' further development on the 7.3 (38r turbo most notable element) was not enough enticement to keep Ford as a customer.
7.3 is a robust architecture and that has great value to me, but it is dated. Newer diesels make more power, burn cleaner, etc.

The 6.0 was a Navistar engine as well. It seems that clean burning diesels and reliability don't go together, although I think some of the smaller clean diesels from companies like Daimler and VW are more reliable. Trying to make big HP and torque and still keep it clean must be a real challenge. Hopefully in the future there will be more advancements which will allow for simpler, more reliable ways to keep the emissions clean.

Besides the horrendous fuel economy and the part about having to pull the cab off the truck to work on the engine?
Stop by and do some reading in the 6.4 section for detailed info on the weak spots and things you can do to keep it on the road.

All the Ford diesels were Navistar until the 6.7L. First one developed in house.
