Check the plug gap, might be a big gap and when it gets hot opens up to far.

Check idle speed . Open idle screw give it more air. Then see if it will start warm.

Check air filter might be choking her when shes hot.

Easiest way to check airfilter is run it without filter.

2stroke or 4 stroke??

Erm worst case is crank seals burning gear oil when shes expanded.

She smokey?

You can try holding the revs up and putting your hand over the air intale if you can.

This will force the engine to draw more through the carb increasing the chances of clearing any blockages in the carb. Dont be shy with it get those revs up and plug the airbox a fiew times. Try keep it running tho dont let it die. Remove the blockage when its about go die.

Then start with carb id say before you condem the crank seals.

It is a process of elimination mate.

You got to go through it one step at a time.
