Omg, it's the starter, just change that and you'll be set. I had the EXACT problem and I was mashing the brakes and the start button because I was so frustrated back in 2016.
This was temperature dependent in my case. The colder it got, the more frequent it happens. In hot weather, like deep south, NEVER happened.
Once I heard the starter was trying to click and verified my battery was brand new, went to FCP and bought a new BOSCH starter. Fires up like a new car.
Here's my thread.
