Dragging
2008 f150 5.4 3v when running down the high way say 50-55 mph I can stop on the gas and it will rev up to 4 grand good and fast but as soon as it hit 4 grand and 60mph it will stop pulling and just sit there and dragg at 60 mph I can let off the gas and stomp it again immediately and it takes off like a champ!!! ive had spark plugs replaced at 100,000 miles it now has 130,000 miles and it has no codes show and all the cylinders show good fire from the mechanics detail please help!!! thanks jimmy

Sounds like a transmission problem. 4000 rpm at 60mph is way too high. I'm not a tranny guy but it's possible there is an issue with your torque converter.
