I have a 2000 blazer 4x4 4 door, when i am going down the road at 65 set on cruise it will be going just fine then its like i get a slight lack of power and stops and then kicks back in and goes. its not like surging or anything its just a slight thing but its get annoying. It does it when its not on cruise also. It did it and then it stopped for a whille now its doing it again.
