HELP!!!! Bike breaks down once warmed up

Hi everyone, my first post and a big one sorry. Any help would be greatly appreciated.
I have a year 2000 GSXR 600 SRAD. It runs fine until up to temperature then it seems to go down to 2 or 3 cylinders won’t idle and conks out. Sometimes it starts straight away but with same problems. Sometimes I have to wait half hour until it cools down then she will run fine until hot again.
So far I’ve changed the regulator/rectifier, ECU and generator. As well as new plugs and coil sticks.
Has anyone got any ideas on what else could cause the problem and any solutions??
Wiring looks good and we have changed the melted connector on the regulator.
Is it normal for this to get extremely hot? Even my new connector is getting hot.
Also is there anyway I can test the ecu, regulator and generator to make sure they working.
Thanks for any advice.

Could it be a fuel issue? Can you tell if it is always the same cylinders that falter? Dirty fuel filters may not be giving enough fuel to support higher RPMs. One or more float bowls may be dirty or filling too slow to meet demand above idle.

I agree with Tinsnips that it sounds like a fuel issue. I would think you might a have float valve not sealing and causing a cylinder to run rich at idle. (flooding it)

So as it begins to falter, what happens if you rev it up? Does it run/ride OK other than idle?
