2002 GZ 250 dies while driving

[Harry4444]

Hey Guys,
New to the forum here! My 2002 GZ250 cuts out on the freeway every now and then and I have to hit the starter to get it to start again. it just dies and lugs down the engine and won't restart by the momentum..? Any help would be great... I've ordered a new rectifier but I don't know if that's really the issue... just an idea.

thanks again!
