The problem may be that we get a lot of people coming in, asking one question, then never replying again.
Might be an idea to go make a post in the 'New Members' area, introducing yourself & so on...

 

It may be that we need more sentences and punctuation (my favourite), long single sentence rambles often confuse people!

 

Or, it's possible no one has a clue (most likely)...

Have you got any more information? It's pretty thin on the ground at the moment.

Does the engine make any 'pinging' noises when you turn it off?
Is it running at a steady temperature?

Is there plenty of liquid in the radiator?

In the 30mins or so that it won't start, does it turn over as normal? Or is there nothing happening?

Hi yeah the bike runs fine with no issues when running you can ride it for hours and will stay at running temperature 

Doesn't over heat or that 

And no noises when you turn it off 

But as soon as you turn it off when it's hot it won't start up again 

But will crank fine and fast enough as to where the starter is getting enough power to turn it over but just won't start 

But once you have let it cool down to roughly 100 degrees Fahrenheit it will start back up again

At the point where it doesn't start, can you bump start it?

Carry a spare plug and check if you're getting a spark, or whether it is a fuel evaporation issue.

Likely a bad engine temp sensor. There is usually 2 one for you and 1 for the fi. If the fi one is a bit flakey the bike might be trying to start 'on choke' when hot. 

Ybrs suffer similar problems.
