Random revving

4WD V6 99-Blazer
When driving at constant speeds between 40mph and 60mph, my Blazer will often start to rev about a quarter of an RPM and then fall back to where it was and then again and again. I thought at first it was trying to die but then I noticed that it was actually revving upwards, not downwards. I usually press the throttle harder and it immediately pushes through it and acts normal after that but has anyone experienced this or have any idea what it could be? It seems to be getting worse.
