Could be a loose connection at one of the sensors, or even balance. Are you running the same model of tires all the way around?

Easy fix, don't speed. Just kidding. Does your truck have front wheel bearing play? My dads s-15 had wheel bearing play. Had so much play that the ring of teeth that the front wheel sensor reads hit the wheel sensor and shaved the top of the sensor off. His problem started like yours but then the sensor just opened. He had to replace the whole wheel bearing and the sensor.

Have you rotated the tires at even intervals? If the rear have lost more tread than the front, they'll be a smaller diameter.

At this point then you need to get the ABS codes pulled to find where the fault lies.
