Couple of things here.
First, the term "cranking" it means engaging the starter. So it's cranking (turning over) just fine and it's not "firing" up.
Second, the rectifier and alternator (stator) have nothing to do with starting it. So replacing those things wouldn't matter anyway. Same goes with the battery. If you've got enough voltage to crank it, that's fine.
Third, the kickstart switch is a good idea, but won't effect this issue. If that was bad, the bike wouldn't crank at all as the starter wouldn't even engage, let alone have problems firing.
Do you let the system fully complete when turning on the ignition and it goes through the self-check? Do you hear the fuel pump priming as this is happening and you hit the starter only after that is done? Have you tried cracking the throttle slightly as you're cranking it over? Try that and see if adding some extra air when trying to start it hot helps at all.
When was the last time the injectors were cleaned? Definitely sounds like a fueling issue. But hot starting issues are hard to diagnose. Time for some lovin' on the bike. Need to check and replace your air filter. Clean your fuel injectors. And synchronize your throttlebodies while you're at it.
I may not be perfect, but at least I don't ride a Suzuki.
