ltr-450 sputters and hesitates after being warmed up.

Having trouble with my bike after riding it for a while. When i say a while,  i mean,  a good half day of riding. Seems to want to hesitate and sputter a bit at low speeds.  Seems to go away once I give it more gas.  It also cuts out at high speed,  just for a split second.  Its almost as if it loses spark.  I have replaced the pancake filter,  new spark plug.  Has anybody else run into simmilar issues?   Could it be spark plug cap,  wire or coil maybe?  thanks, mike

i would check the cap, wire, and how much gas is in it. all have been problems with others i know.

u know i had basicly the same problem with my rubicon. ran fine for over 2 hrs one day then it started to sputter. next day started it up ran fine. then like a week later it acted up again. i would have to choke it to keep it running. all i did was just go through the carb and clean it out. ran fine since
