Won't start after 45min.
 

I have 99f-150 130,000mi.
Has been running great never a problem, new batt.
Seems when i have driven it for around 45min. letting it sit for 1hr.
will not start for another hr. I just get a clicking on the inside nothing is getting to the soleniod. everything in the cluster sweeps, no blinking lights, just click click. Everything looks tight. Sits over night, starts right up.
Will also start up right after stopping it. Any ideas?

Starter. ;)

Thanks Bluegrass

Starter or perhaps a bad cell in the battery. Check the starting system and battery. Although, if its gets hot and the solenoid is the problem it wouldn't be suprising.
