It would help to have a bit more information. When you say it starts and warms up will it keep running until you stop it? Then when it's hot it won't start? Or does it die once it gets hot?
The first thing you'll have to determine is whether it's an ignition or fuel problem. A spark plug tester or just a spare plug can help there. Remove the lower fairings so you have access to the spark plugs.Start and warm up the enginethen shut it down and see ifit will start.If not,insert a spark plug tester or disconnect one spark plug and using a spare plug, insert the plug into the spark plug connector and lay the plug on the cylinder head to get a ground. Then try cranking your engine and see if you have spark. If you have spark at the plug the problem is probably fuel related if you don't it's most likely ignition problems. If there's no spark one possible source of the problem could be the pulse coils mounted under the timing belt cover on each side of the crank pulley. Often when these go bad they fail when hot and then when cooled down will work again until they get hot.
