i have a 97 ford ranger 4.0 5spd 4x4 if it runs for an hour or a few seconds and i try to start it agian it will only turn over and not start has spark i can hear fuel pump. help is greatly apreciated
I think the spark is ok, it starts fine when cold, will run fine even if it's a hour or two. Just when it's shut off I have to wait a couple of hours to restart, even if it only ran for a couple of seconds.

If it dies when hot it could be vapor locked, check where the fuel lines are running and are not near the exhuast manifold or anything else that gets really hot.
