So I found that this is not unheard of:

When I'm travelling at highway speeds for awhile and then pull in the clutch after coming off I see the tach wind down, hesitate at 1000rpm and then stall.  It doesn't happen if I'm just switching gears only if I'm skipping down gears while slowing down.

It starts again right after, both at a standstill and on the ramp.  If after pulling in the clutch i blip it between gear changes it works and doesn't shut off.  The bike idles at 1400 after warmed up.  I set it to 2000rpm and the issue still happened so I set it back.  It's less common with choke on but still happens sometimes. 

Am I just switching gears wrong?

no, that's definately the bike and not you.

does this happen at road speeds (like 40mph in 4th at 5krpm + clutching = stall) or just highway speeds?

Lowest speed I've seen it happen is 80kph, so about 50mph.  Usually coming down from 6th gear, but I've also had it as low as coming down from 4th when I was trying to determine the revs it would occur at.

It seems like it happens when cruising above 5500 rpm for more than a few minutes, but it's not consistent.  Sometimes it works fine and I can't replicate it exactly every time. 

Stands corrected

What? It's not clutch slipping.

Fuel starvation caused by higher rpm's maybe.

So as I understand it, you're pulling in the clutch and holding it in while you down shift from top gear all the way to bottom and are just rolling and slowing with the aid of the brake? You are not downshifting then reengaging each gear briefly before pulling in clutch and shifting down another gear?

We've had somewhat similar discussion before how brakes are cheaper than gears and engine and yadda yadda yadda. Nevertheless, *I* suggest to Always reengage gears as you slow so you are always in a better gear for reacceleration and the engine is already revving and ready for you.

I usually skip one each time so like 6-4 then 4-2 then 2-1 (through N) if I'm coming off the highway to a stop.  But when holding it in between 6-4, it dies if I don't blip it. 

Mine will do this too after about 30mins of freeway driving at 70+.  I just keep it alive with the throttle until it gets its street legs back.  It only takes like 10 mins to get back to normal for me.  I have also had the fuel starvation when reaching for top speed as well.

So bike limitation?

Again, this is not unheard of.  Some say that the petcock doesn't flow enough fuel at top speed, others say the bike's jetting isn't setup properly.

I haven't experienced that with any of my 3 bikes.
Then, I have replaced the gas caps (maybe the tiny air vent on your gas cap is plugged?)
I have replaced the tanks and fuel lines on Junior and Trey. also the tank fuel valve and in-tank screen filter were replaced. So possibly your in-tank filter is dirty or fuel line problems.
Maybe I'm just lucky or maybe everything is good to go because I have replaced some of the old parts.
