ABS Traction control issues in 05 Expy

[dano]

Hello, Just tonight, I was leaving a friends house in my 05 Expy. Upon leaving the driveway, she started crow hopping like it was in 4 wheel drive. As its doing this, the Traction Control light is flashing very fast, and I realize it the brakes that are trying to engage, even though I am not using the brakes. I then shut the truck down for about 20 seconds and started it back up, now both ABS and Traction control lights are flashing, then it took off like a bat out of hell. The two lights stayed on then. When I got home, I shut it off, waited 15-20 seconds and started back up, only to have the ABS light on.
What the heck could possibly be wrong?

Update... started it up this morning to go to work and all idiot lights out!

Odd timing, just had this happen last week. Only happened once.
