Answer 1

i own a repair shop,,and i don't think its vapor locking ,,i think it might be starving for air,,the breather may be stopped up on it,and hot air doesn't flow as good as cool air does this would explain the heat deal,you can always try opening the gas cap and releasing the pressure on it and see if it has any built up behind it,,this sometimes will help one to start,but other than that id try checking all my breather parts and make sure it is getting good clean air,,if all this fails then it may have a bad sensor on it giving false reading on the computer saying its already warm and the computer will not allow the needed amount of fuel to flow to it to start it, good luck maybe this will help some.

Okay - it is likely that this is only happening when you are low on gas, right? like maybe a quarter or less? You could be suffering from vapor lock - fuel expansion inside your tank and fuel lines, that prevents liquid fuel from passing through. It's like when you take a glass, hold it upside down, and put it into a sink of water...the water doesn't go in the glass, does it? No because the air keeps it out of the way.

Try this: Keep your tank as full as you can, and also, buy a new gas cap. These two things will probably help you a lot.
