Agree with all of the above zirconxi, what brand battery and how old is it?
Here is a chart explaining the relation between operating temperature and battery life;
and the relationship between temperature and capacity ( a different subject ).
As Lord Popgun mentions; check these 3 connection points; 1; battery ground at the engine block for corrosion, 2; battery negative and positive at the battery, 3; positive terminal of starter relay.
It does seem counter intuitive looking at the temp/capacity chart that the bike starts when cooled down which makes the starter cables a bit more suspect but normally when the meters sweep the capacity is too low if the cables are reliably connected, the bike's electrics are supplied from the battery terminal on the starter relay ( the two heavy fuses ) so that rules out the starter relay itself and after that.
Batteries are best at 20 degrees C. for overall performance as the chart suggests.
Seem to remember you replaced the battery not too long ago.......could be time to look at a lithium battery in your hot situation but i am puzzled as to why you have your problem but if the battery can only handle 3 start cycles it is time for replacement.
The system voltage on my bike is very close to 14 volts, if the voltage is constantly higher than 14,5 volts during riding the battery life can be shortened.
Also seem to recall that sometimes the fuel gets to a boiling point at a stationary situation when the fuel rail gets warmed up by the engine heat;
