I have an hardbody with an yd30 engine it starts when its cold but as soon as it reach operating temp it cuts out and wont start again

Other electrical items such as crank or cam sensors, ingnition modules, coils can act this way as they can have hair line cracks in a winding which opens up as they heat up. Even a fuel pump can do this, so using diagnostic tests such as fuel pressure gauge and timing lights (to check if spark is getting interrupted) are sometimes helpful. These are hard problems to locate as the part may bench test good but still fail in use.
