If it has been running for quite a while without problems and just started doing it, i would go with eden and say electrical and try a different stator or CDI unit. Could just be doing it in fourth as it will put a bigger load on the engine in fourth gear.
Only other thing to check on your fuel system is a worn needle valve but it would probably do it in all ranges if this was the case.
