Try this: Start the car and idle for just a couple minutes, THEN let it sit for a couple days and try starting again. If the problem is gone, then the cause must be fuel boiling out when the engine is hot when parked (I think it's very unlikely it would boil all the fuel out). If it starts hard like usual, you have a leaky carb, it's probably bleeding all the fuel out into the intake while sitting parked.

This sounds like a good idea to me. It would show that there is a fuel leak or it is boiling out on a hot shut down. Another option may be to pop the hood and try and get it cooled down quick after driving it. I pulled my car in one day when it was hot and heard a muffled sound like a drop of water dripping into a hot pan. I pulled the air cleaner and saw fuel dripping out the accelerator pump nozzle on my holley. After it cooled a little it stopped. I imagine it happened often but never caused a starting problem.
