Engine problems of the 2003 Mazda MAZDA6

Over a period of 1-1/2 hours, our 2003 Mazda 6 quickly lost all acceleration power on 5 different occasions while driving out of town on the highway. Following a 'slight bump' the car went from 70 mph to 35 mph to 10 mph, quickly, regardless of pressure applied to the accelerator. Getting to the side of the road in traffic going 70mph+ was in itself a challenge and after pulling to a complete stop the car began jerking fiercely. Only turning off the engine completely was the system 'reset'. The Mazda dealership hooked it up and determined the throttle body must be replaced for a quoted cost of $534. 41 (macon, GA). The sensor itself, the likely culprit for this issue, is not offered or available for sale by Mazda without its 'body', unlike countless other makes, which is outrageous, but the most disgusting part of this issue is that although there are a critical number of complaints logged about this issue, the tps has not been listed as a recall. The dealership stated they did not have to replace it since there were only 'service bulletins' listed and no actual recalls for the parts. They are very aware of the situation. From my own experience and my daughter's with this issue, I can guarantee that this has definitely caused serious injuries, if not fatalities, that just haven't been reported or possibly identified. I will continue to hunt down the sensor as I will not fall prey to Mazda's 'racket'. The car will sit until I locate the part, or end up being parted out.
