After driving about ten minutes my anti skid service light comes on. The transmission shifts down and there is reduced power for take off. I noticed that the cruise control does not work at this time. Like there is a loss of vacuum. Hence the transmission shift. I have unplugged the yaw control also pulled fuses to the ABS with no change to the problem. Also on the dash shift indicator it goes from D (drive) to like there is a loss of computer command. I can turn the car off and drive again and the problem starts all over. Driving on the highway the car will increase in speed but not shift. Thanks!

First thing you need to do is have the system scanned for codes. You would need an advance scanner to read the ABS module to get the codes. If you can retrieve those codes and post them on here that would help.

You made need to reset all codes and drive your vehicle again to get the light to set again since you started unplugging sensors and removing fuses you may have set more codes in the system. I do not see the yaw rate sensor causing reduce power. You may also have engine control module codes set also which will cause the reduce power. Maybe a faulty throttle body? But you would need to post ECM and ABS codes to see what is going on.

Also if your steering wheel is off centered bad enough, it will reduce power because the system may think your over steering at high speed. In that case an inspection of your suspension and maybe an alignment with resetting zero point calibration is required. Let us know by posting codes or if your steering wheel is off centered.
