REad codes get P0172 and P0174. Read the forums folks say mostly likely MAF, just replaced the MAF took for a spin and the same thing just happened. I didn't push it the SES point yet, but I can reproduce. Any other thoughts or ideas? I'm gonna try fuel system cleaner, then maybe fuel filter but man I am stumped.
thanks

I'm having the exact same problems. The car starts and idles perfectly but when I apply more than about 20% throttle, the engine cuts out and feels like the fuel is getting cut like it was hitting the rev limiter. If I don't apply more than 20% throttle, the car drives fine and shifts through the gears. I can even rev it up to redline in park as long as I don't apply more than 20% throttle. It also threw P0171 and P174 codes so I replaced the MAF with no success and the problem still exists but the SES codes have not come back.
Has it been confirmed this is a problem with the DSC modules / ABS control unit? Can anyone tell me the part number for this part?
