Hi,
The first thing I suggest is to have the battery load tested and the alternator checked. I realize the vehicle starts when cold, but when after being driven, it is hot and the battery, if not being properly recharged by the alternator, can cause this. If the battery is good, it can, to a degree, come back after being slightly drained when given the time.
Here are a couple links that you may find helpful. One other thought, make sure the battery terminals are both clean and tight.

Do this first and let me know the results. Also, I suspect the starter is good and isn't being affected by heat. If it was, it would do the same thing when jump started and you said it doesn't. That is what is leading me to a bad connection at the battery or something is allowing the battery to get weak.
I will watch for your reply.
Take care,
Joe
