I have a 98' Dodge Durango 5.9 stalling

What is your question?

The truck warms up for about 15 minutes no matter where it's at, on the road or sitting in the driveway. About that time it stalls then I would wait a little bit to start it over again. Then it happens again. It stalls. Just earlier it won't turn over anymore. It kept making a cranking noise. I just recently added a new fuel pump and a brand new computer and battery. I checked all the connections on the battery, I even used a different battery and still won't turn over. Any suggestions?...
