Hey I'm not saying that there aren't other reasons why an engine might quit on a hot day... I've had bad coils as well.
Chevron publishes an extensive study regarding modern fuels. Look up 69083_MotorGas_Tech Review.pdf on the internet to download a copy. It's important to consider that gasoline is formulated to perform best in engines that are most commonly used. Today that means a closed and highly pressurized fuel system. Running more volatile blends in our older cars can on occasion cause unintended problems. Even mixing summer blend into a tank that contained winter blended fuel can be an issue.
In my case, it was easy to determine whether I had a fuel or spark issue.
