So low RPM, in gear, wheels turning, steering input , then dies, correct? Any stumbling, rough idle just PRIOR to the event? Idles normal in neutral? How about in gear? Can you feel the downshifts when coming to a stop? Does the trans drops down into FIRST every time you come to a complete stop?
Quick test: Warm engine, in gear, blip throttle. Does the engine increase RPM and return to a even idle without hunting for the right RPM? Watch the tach, if the engine module is having trouble establishing idle RPM based on vac leaks, IAC, EGR etc it will fluctuate all over trying to level out. Same would be true if you power brake the engine and try to hold say 1,000 RPM. High vac signal at the throttle body exposes all the weak areas.
Post your findings and maybe we can point you in a right direction. Otherwise WE B Guessing.....
