2002 chevy express 2500 extended van. If it matters...5.7 motor / 157K miles on it.

Both yesterday and today, my ABS light came on after about a minute of driving. After getting to my location, which was only a couple mile drive. I turned the van off and back on and the ABS light was off. It also didn't come back on during my drive back.

Thoughts?

 

would be a poor wire connection. i know on my imp the wheel sensor wires run between the spindle and cv axle. they rubbed and under certain conditions my abs light would come on, i would turn the key off and back on and abs light would be off. replaced the wheel sensor (hub bearing ***.) and problem wet away
