'94 SL500 no start when at operating temp

[jcciem]

Having a problem with my '94 SL500. Car when cold, starts and runs perfectly. As soon as it reaches operating temperature it will do one of two things. Either start stalling repeatedly, eventually reaching a non-starting state altogether just with occasional exhaust system popping. Or it will continue to run perfectly until shut off. At that point any attempt to re-start the car will not be sucessful, just the same occasional exhaust system popping. Any ideas?
