2005 Sequoia Stalls after cornering (solved)

My 2005 Toyota Sequoia was experiencing power loss, stalling, failure, holy shit I have no power, my engine just dropped out and I am in traffic. I have been experiencing this for a year or more and it was getting worse leading up until now. I was at a loss, my wife was scared to drive the truck for fear that it would die and stay dead. What it did do was after making a corner, whether stopped or rolled through, then applying the gas, either WOT or easing into it (pulling into traffic). So in a scientific manner I made laps last night getting the power to cut out every single damn time.

Some intense internet researching with different keys words landed me with the suggestion to conduct a zero point calibration. The only thing was that the folks saying this should be conducted had VSC lights on and holding on the dash. I though what the hell it couldnít hurt.

Did as the instructions said, then drove it again. This time the VSC engaged with the blinking skid light, then an audible alarm, then reduction of rpms, for 1-2 seconds, and back to normal. I could not get the truck to repeat the loss of power for no apparent reason. Zero Calibration worked in solving this problem.

2005 Toyota Sequoia SR5 2wd. This is extremely frustrating but we will get through it. The murder sequoia is still at it trying to kill me. To date I have unplugged and run the vehicle with the following. VSC plug on the brake fluid reservoir, lights (VSC, Trac, ABS) came on no change in performance. Yaw control module under the center console, lights (VSC, Trac, ABS) came on no change in performance. I have also replace the throttle position sensor (non wire on the 2005) with a used one, no change in performance. Replaced the Mass Air flow sensor because I had a trouble code, no change in performance.

What other sensors feed the VSC or ECU that would shut the vehicle down almost every time at the same set of environmental and input variables? Steering position sensor? Trans Fluid change? Rear shocks? I just donít know but itís to the point that Iím thinking about a low mileage 2007.
