Hi,
I have to be honest, even when it started, it sounded like it turned slowly. I want you to check something for me. Drive the vehicle to a parts store and ask them to load test the battery. Most do it free of charge. If it passes, there is a relay under the hood called the starter cut relay. I'm questioning if it is bad. I attached a pic of the component. The reasoning is it stopped itself from cranking and other times you get nothing.
Here is a test for checking relays:

If the relay is good, the battery is good as well as all connections, my next step would be the starter. Here is a link that explains in general how one is replaced:

Here are the directions specific to your vehicle for both replacement and testing of the starter. The attached pics correlate with the directions.
