Wouldn't expect so, but does it have a cat fitted? Could be something silly like an exhaust restriction anyway!

when it dies, is it like an "rev limiter" dieing or more of a spluttering kinda dieing ?

like a rev limiter, once it hits around 4k it does it. so if i leave off the throttle then back to idle, it splutters for a few seconds then back to running normal , you rev up to the 4k once again and same tin happens.?
