This problem may be due to fuel leakage.

Assume that you have a leaking injector or regulator. When you shut the 
engine down, the fuel system holds pressure as it should, so the faulty 
component continues to leak into the intake manifold, filling it with fumes.

When you try to crank the engine, it is flooded, because of the leaked 
fuel, so it won't crank. You keep trying, and eventually try cranking it 
with the throttle open, so it clears, and would crank - except that the 
fuel pressure is low, because of the leakage. Now it won't crank because of 
a lack of fuel.

Try this - when the engine is hot, push the throttle to the floor and crank 
for two two second bursts, then release the throttle and continue to try 
with another couple of two-second bursts.
