I will be driving around town and seem to have plenty of power, but when I hit the highway and exceed speeds of 55 to 60 miles per hour a have a loss of power and the truck will drop from 60 to 70 miles per hour and drop back to 40 to 50 miles per hour! This is even worse when clibing a hill it dogs done and I have to let of the gas to regain some power! My truck is a 1995 f150 4x4 ford pickup!

Note: I have replaced the Fuel filter on front Tank and that did not fix the issue also!
