Turns over but won't start

Your engine is either missing spark or fuel. In theory could also have a significnat exhaust restriction or air intake issue. But probably a spark or fuel issue.

My 2002 Ford sport trac has the same problem. It turns over but is not getting gas to keep going . If you find out what's causing it let me know mines in the shop now gas is half down and it hasn't done it in front of the repair man of course so they don't know what it is
