I would start by replacing the ignition coil. If the coil is defective, it will act up when the vehicle heats up and you can have a no start condition.

A long shot would be a bad crankshaft position sensor. I believe they can act up when the vehicle is hot as well. If it's the crank sensor, your problem will get worse until the vehicle no longer starts, even when it is cold.
