Engine will not start

I have a Robin EC13V 2 cycle engine on a Snapper mower deck.  Engine runs great when started cold, butI have some trouble with starting after mower gets hot and sits in the sun for a while.  If I put the mower in the shade and wait a while the mower starts fine.  I have been through the carburetor a few times, but not sure what I am looking at.  Any suggestions?
 
Thanks

    It sounds like vapor lock. Is the fuel line close to a heat source? You might try wrapping it with foil.

    In some of my past endevers with some old 2 cycles they run the best when cold as in like drag racing possibly maybe compression issues or crankcase vacume leakage kinda guess like I'm taking a wild guess

    Sounds like maybe a coil issue. Ha e seen that often when they won’t run or start when they get warm

    There is some minor issue in it because whenever it heat up, it turns off. May be plug issue or any wire which is not working properly when it heats up.

    All good answers. Many times when an engine heats up it can develop a slightly lean condition which can exacerbate other problems that you may already have.
