Hi and thanks for using 2CarPros.com.
Since you get a click and then eventually it does start, it sounds like either a dirty or loose battery connection or the starter is going bad.
Based on your description, it sounds like a dirty or loose connection. Unlike water, metal expands when it gets hot. Thus, a connection can be tighter. Take a look through this link and follow the directions for checking, cleaning, and tightening the connections.
If you determine that the starter is bad, here are the directions for replacing it. The attached pictures correlate with these directions,.
1. Open Hood.
2. Disconnect the negative battery cable.
3. Raise vehicle and support.
4. Disconnect the electrical connector from the O(2) sensor.
