Fuel injected engine ?
when it does finally start, how does it run ? smoke, smell etc ?
when it's failing the hot restart any fuel smell ?
I agree with Jim, this type of problem should be easy to diagnose by any competent technician.

post more info if you want anyone here to try and help.

sounds like the injection system is losing residual fuel pressure making for difficult hot restarts. hopefully Jim can hook you up

If the air temperature is high and the motor has been run hard, it'll heat soak when it's off and the coolant temperature will increase to the point that the ECM thinks it has overheated. This switches the injector banks on and off, making it very hard to start. leave the motor box open while the motor is off and try it that way. If it starts right up, you'll know why. They had the same issue in Arizona, Southern California and Texas when these motors first came out and they had a recal for it. If the dealer didn't get the memo (doubtful), they wouldn't have done anything about it. If the original dealer went under and the new one didn't know which recals were implemented, ditto. Have the dealer hook it up for diagnostics and write the checksum and all of the other data on a sheet of paper and fax it to the technical/warranty department at MC, so they can see if A) the checksum is current and B) if there's anything that's apparently wrong.

If the fuel pressure is dropping, turning the key on so it can prime before cranking should get it to fire up immediately. If it takes two or more 5 second crank cycles, I would be looking at the fuel filter(s) and the screen in the pump inlet.
