Most likely ou have speed sensor that Is not giving the correct info. At startup the abs does a self check and since the light stays off until you drive it there is no issue with the systems integrity. The light comes on after you start to move because the system is not seeing the info it should be seeing.
Your best course of action is to have the abs system scanned for trouble codes. This will help narrow the possibilities. Once you have the codes post them here.

SOURCE: 2005 Chrysler town and country abs light on, but
We own a 2005 Chrysler Pacifica (3.8 litre) and currently have the same problem. This has happened at least 2 other times on our vehicle. Our trouble code was for a faulty ABS wheel sensor, and after searching the internet I found A LOT of other Pacifica owners had the same problem. The first time this happened to us, it was covered under the Chrysler warranty. The second time, it cost about $275 to repair. This is something that only a Chrysler / Dodge dealer can diagnose and repair. At first, we went to Firestone and they preceded to replace the brake pads, rotors, flushed the master cylinder and nothing they did seemed to work. Finally, I went to the Chrysler dealer and they immediately diagnosed the problem and fixed it. I am not sure if the computer will actually report a trouble code for the ABS problem or not. I will warn you that even though the brakes seem fine, eventually they WILL fail on you and you will have SIGNIFICANTLY reduced stopping power. Our light went on while we were down the interstate at 70 mph, and let me tell you that was a very scary situation with me, wife and two kids with NO CONTROL over how fast we could stop. Take your vehicle to the dealer and get fixed, it's not worth risking an accident. Good luck!

check rear brakes also, for grinding, could be metal to metal surface contact, you may need to have your abs codes read with a scan tool for ABS brake system, you do not want to take short cuts or even guess when safety items are concerned , and Brake system is definately in this category, have a qualified technician inspect if you are unable or unsure of the proper procedures... could be something simple but may be not...
SOURCE: brake and ABS warning lights on, trac off on.
You may have a bad abs controller. You need to get the code for the abs light from a shop or auto parts store.

Did you use the correct brake fluid? Did you put custom wheels on your car? Do you have a leak in the brake line? Make sure that the brake boost hose is attached to the air-intake on the top of the engine to the left side. This is a black rubber hose. May be one or more calipers are sticking unnoticed to your braking. check you master cylinder to see if it is working.

sounds like your alternator is going out or have a short
