2000 Nissan Almera • 6 cylinder 2WD Manual • 72,000 miles

Nissan almera 1.5 s stutters at fourth and fifth gears but goes beyond 70mph on the third without any problem! Does beyond 4000 rpm without any trouble on the third but the moment I change up it begins to loose power like there is no fuel in the car (though there is enough) please help
