I have a 2005 durango and it happens to mine also. But it only dies when in idle or low speeds under light or no loads at all. When running in high speeds or exiting the highway it runs fine and it only does it once in a great while. The funny thing is that right after it happens, even before I come to a complete stop, I can start it up right after and it runs perfectly fine! go figure, cause I can't figure it out!
