Sounds like an ABS problem. Pull the fuse for the abs pump (light will come on) and see if it still happens.
Most likely a failing wheel speed sensor.
If he has multiple sensors giving false readings he may very well have no brakes.
With an ABS capable scanner, you should be able to see which wheel sensor thinks a wheel is locked up. It won't throw a code, because it thinks it is doing its job.
once I pulled the fuse, stops perfectly fine. I have a bad wheel sensor that never once threw a code.
To the OP, pull the abs fuse under the hood and try it.
You were all right, I pulled the fuse and went for a drive without it happening once. Normally it happens before I get to the end of the spur I live on (about 100 feet). Now to get the codes pulled and the thing fixed.
Thanks to everybody for the help, you saved me some $$$ for sure
