Did you get to the bottom of this problem as my sons YBR 125 is having similar problems, Have cleaned carb changed coil, new plug and plug cap but still cuts out after running when gets hot then leave for a couple of hours and its ok again, then after warm will cut out.

Have you sorted the problem yet? My son has the same problem with his runs fine for 30 mins then just cuts out and wont start, We have changed spark plug, had the carb cleaned out and had the valve clearances checked just this morning but still the same problem, Just wondered if youve had any joy with yours cheers Nick
