A hard time starting hot when cold starts are fine is the primary method we have of identifying engine compression loss.
Get the engine compression tested at a Mazda dealer. See the new owner's thread, post #8 i think, for information on what you are looking for, why it needs to be a dealer performed test, etc...

Define "fine"?
Should be compression numbers on 6 rotor faces and 1 or 2 cranking rpm. Without all information like that, compression tests are worthless.
A "fine" compression of 7.2 isn't driveable if the cranking speed is 300rpm, and is a stellar engine if the cranking speed is 200rpm.
There is really only 1 other possibly for hard hot starts, but you haven't given any symptoms that suggest it (because it causes more problems while driving than it does while cranking).
