If a radical change in power output and it seems to run fine down low but hits a solid wall and any more throttle just makes engine get louder with no increase in speed then look at cam timing belt, it may have just jumped a small amount. Mine did that, couldn't tell it until 35 mph where car stopped like with a rev limiter on it. One quick check may be yanking top belt cover and look at belt condition, mine had backside scraping and small cuts that indicated a pulley went south, locked and started dragging belt to derail it a couple teeth. Car idled perfect and seemed to rev normal when whacking the throttle.
