I was traveling home from Texas City to Denton and had the truck on cruise for about 20 miles and it suddenly kicked out of crusie and the ETC light came on and the truck was running a little rough when i would let off the throttle. I pulled over and got something to eat and when started the truck the light was off and it ran great the whole rest of the way home. It hasent happend again. Why would that happen?

 

My 09 5500 has done the same thing a couple times. When I continue driving and leave the cruise set to 60 mph it goes b/n 50 and 60 mph. Then it seems to go away. It is going in for an oil change next week so I will have it addressed then I hope.
