I went through the same issue.


Get to the starter and I think you'll find the ground strap from the solenoid to the motor will be loose. In my case, the resistance created enough heat after enough attempts to actually create contact and the starter would crank.

Replaced the starter and all has been well since.
That cable sits right next to the driver side header and is exposed to elements. Enough heat cycles and wet weather and corrosion/fatigue from a vibrating engine will degrade these.

Here is mine at 110k, fell apart in my hands when I removed it.
