Most likely causes: Either you have a weak battery (has a 12-14 volt static reading, but unable to put out the amps/power needed to run the starter), or your starter is failing. It might help to check the starter brushes and clean the commutator. Also, have your battery checked, or just replace it with one you know is good.
Generally it takes a greater level of battery power/stronger starter to start a hot engine, since the engine tolerances are tighter due to expansion.

This is what I do for fun, not for work. It is art, with a little engineering thrown in.
