Sounds like a broken wire at one of the abs sensors or a bad sensor
This car needs to be scanned with a scanner capable of reading body codes, if the light is on the BCM or body control module has found something wrong,get the code and get back to me. most scanners at the parts stores will not read ABS codes. Hope this helps get back to me Thanks Ray, please rate my fix?

the most common thing that causes this problem, other than spinning in mud, is a wheel speed sensor. the best thing for you to do is get your car scanned. autozone offers free scanning. i have seen many hub bearings go bad, come loose and cause this. if the problem comes and goes the hub is likely the culprit. i have also seen cracked abs rings cause this at higher speeds, i have also seen the harness running to the rear wheels torn out from running over tree limbs. i would definitely start with a scan to narrow down possibilities and save you money done by guess work. you can try jacking up each wheel and shaking to ensure that all bearings are tight. if you have access to a oscilloscope you can backprobe each sensor while spinning the wheel and find which one is breaking down.. hope this was helpful... dustang

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.
