if it wont do it at lower speeds and only does it after being on the freeway at high speed for 10 plus miles then might be coil. when coils start failing they usually start acting up at 10 to 20 miles of high speed. another thing could be your valves are adjusted too tight. they might be heating up on the highway and not closing all the way because the valves get longer when hot.
