    Try This?

    The 3.0 has a camshaft syncronizer they were notorious for going out in the late 90s they usually go out between 80,000 and 130,000 miles. When it fails there is usually a "belt squeak" which is followed by a shut off. If this shut off occurs and the truck won't start afterwards it could mean you have burnt valve due to the cam sync and sensor failing.
