My father-in-law has a 2006 Ford F150. Will only start when it is cold. After running it for a while and cutting it off, then try to restart, it will not turn over. Voltage shows good and all electrical inside works. Checked battery, cables, and starter, all are good. The engine has to be completely cool before it will crank. What could cause this problem?

When it doesnt crank see if the yellow wire with a light blue stripe at the starter has power with the key in the start position?If it does then bad starter it may have tested good when when it gets hot it could be failing.
