have you scanned the computer to see what the code is? scanning it will better help to understand what is going on. if it is a 1996 or newer auto zone will scan it with there scanner for free.
from experience with gm cars and trucks if the light comes on at high way speeds it usually has something to do with the egr system.
but you can't be sure what part of the system is malfunctioning until you get it scanned but i am sure you will find it has something to do with that system.
good luck

If there is an AUTO ZONE around your area, have them scan the truck for any DTC codes which would help us understand why there is a check engine light at high way speed. It could be a misfire to transmission problem, to having the engine run lean or rich to a faulty fuel pressure regulator. Good luck and keep me posted, be glad to help get your truck running 100% again soon.
