Ruckus losing power after cruising a while

Hey folks,

I recently re-assembled my ruckus after it was in pieces a couple months to get things powder coated. Prior to tear down, the scooter ran perfectly. Since putting it back together, I've had an issue where I'll be cruising around for 5-10min and then the scooter will lose power and will only idle. After pulling the side of the road and turning it off and on, the scooter will again run fine for a couple minutes but then lose power again...so on and so forth. I do wonder if there's something temperature related because the first bog down usually takes longer than subsequent ones.....thoughts on the issue? I have already cleaned the carb and checked the spark plug.
