Had the exact same issue as you do now, the fuel accumulator is the first thing I would check.

If it is damaged when the car is warm the fuel turns into a gas in the fuel lines to the motor and when you go to start the car you get vapor lock. It will eventually start once the fuel pump has run long enough to cool the fuel back into liquid.

The accumulator holds a reserve of fuel in liquid form for warm restart, if the diaphragm is damaged all the fuel drains back in to the fuel tank and you get warm start problems.
