It is my friends car. the problem is when it gets warm it will die and will not crank back until it cools some. We have but a coil, and a control module on. Neither of them helped. any one have any idea's?? Maybe pick-up???
How are the engine / chassis grounds? Check the wires running to the starter also. As heat builds in the engine bay (heat soak) the resistance in all of the wiring also builds. When the resistance is great enough, your stater will not recieve the nessecary voltage needed to crank the motor.
