When truck gets to a cruising speed of about 70 engine light flashes. It sometimes even goes into the reduce power mode which requires you to stop and then it runs fine again. It always runs good as if nothing is wrong.

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.
