600RR 03 problems when the bike hot

hey guys, first of all, sorry for my bad english.
so I bought my self 600rr 2003 one month ago and have two problems, maybe someone here know where to start.
I live in a very hot country (Israel) and the temp gauge is always between 96-110 I thought there is something with my coolant system but I found this forum and saw a post about the temp.
the first problem, after 20-30min of riding, if I turn off the bike and start again, the starter sounds weak like the batt is dead, but if I let the bike 15mins to cold down everything back to normal.
the batt is new and when the bike cold it starts with no problem.
another thing is after 20-30min of riding if I pull the clutch on low speed, to shift down or slow down on traffic or on a red light, the RPM drops under 1K and the bike turn off and again if I let him to cold down like 15mins everything back to normal.
most of my riding is when it's 31C outside and some times 34C, but last week I took the bike for a ride early on the morning when it was still cold outside (you know desert, hot days cold nights)
and the bike didn't had any problems at all and that's why I think maybe its something with the coolant system.
I must say I don't redline the bike and don't know much about the history of this bike, till now I changed the oil and batt. next week I want to take off the fairings maybe I will find something there, change spark plugs and valve check.
if someone here has any idea where to start and can help me it would be awesome.
safe riding to everyone!

I would check the stator output and the voltage regulator to start

hello, a little update... still didn't find the problem.
I took off all the fairings to check the wires and found a bit of corrosion on starter relay, and on three relays on the left side of the air filter box, cleaned and put some grease on the connection.
found the throttle body dirty and cleaned it.
found two intake valves that needed a little adjustment.
spark plugs are fine but I ordered a new one.
after that, I let the bike to work outside and check the charging everything is fine, but when the fan starts to work volts drop below 13v and bike turn off. so I change the voltage regulator and the battery for check and still the same problem.
so there is something with the fan but I have no idea what to check next.
any ideas?
thanks a lot

what brand of battery do you have? if its a cheap battery it might not be putting out the 190cca to kick it over...

Check the stator output. Make sure it's charging
