Lexus GX 2004-09 :: No Acceleration After Traction Control Engages

I've noticed when driving our 06 GX this winter, that after the traction control engages on ice for example, it leaves the car with about 20% of it's normal power when you hit the gas, like it acts as a fuel shut off or something. It's been potentially dangerous if you aren't ready for it.

We have a had a lot of ice in upper Illinois this winter and I've been blind sided by what happens a few times. The worst is trying to make a left hand turn from an icy street. A lot of our side streets don't get the attention from salt trucks like the main roads do. For example, when making a turn off of an Icy side street, onto a street that has no ice. Wheels slip a bit initially, you hear the Trac kick in, then gimpy mode. After making it off the ice, the car has almost no power to accelerate, even after it's on dry pavement for as long as 10 second or so. Really dangerous when turning into a busy highway. The car just won't go. Then all of a sudden, boom and it's off again like normal. I would think that things should go back to normal on dry pavement pretty quick but the delay is pretty long.

Is this normal? Is there any way to disable the traction control in this situation? It's like the truck shuts the fuel off ( I know some Trac systems work this way). I'm definitely not one that hammers on the gas either, as soon as the tires sense a little slip it seems to go into this gimpy mode. Otherwise, everything else functions as normal.
