Fails to start warm

My car starts very easy when sitting in the garage. After a 20 to 30 minute ride today, it failed to restart. It was very hot here, about 90 to 95 degrees. This has happened twice now. Today, I waited about 20 minutes and it started right back up. Last week it started with a jump
( hence the new battery) but it had still sat for 30 minutes or so.

I got a new 6 volt battery last week and I am using mid grade gas with Star-Tron Enzyme additive. It is has been running perfect when started.

I know there are many experts out there,
What do you think is causing this
