Vapor Lock?

Since you had a valve job done, they would have cleaned the valves, so I doubt that is the problem. Perhaps the injectors are dirty.

I would perform a fuel pressure test, and a leak down test. If an injector(s) is dirty, it may get stuck open when the engine is off, and allow the fuel pressure to bleed off.

Our cars fuel pumps don't charge the system in the 'on' position before starting, like some other cars. So it might take a few more cranks to build the fuel pressure up, and allow the car to start.

Also...it could possibly be an electrical problem. Either a connector, or even an electronic component that gets problem when it reaches a certain temperature.

Believe me, I've seen some very weird things in vehicle electronics.
