2009 Nissan Frontier loose power and hesitation

Engine Performance problem
2009 Nissan Frontier 6 cyl Four Wheel Drive Automatic 15000 miles

After trany lock up in or out of o/d there is a bad lose of power. During slow acceleration @ 40 mph on a slight up hill grades, keep depressing gas w/ no response the truck starts to skip or lurch then it will down shift. I have started feeling that lurching at higher speeds now but is only present when accelerating up hill grades or when the truck is more taxed. The dealership is trying to say it's normal tork lock up " normal operation".
