Crankshaft Position Sensor problems of the 2000 Chevrolet Impala

No warning, no event leading up to the failure. 2000 chevy Impala LS 3. 8 stalls constantly. No check engine light comes on, so there is no way to know what is causing this. Seems to be a common problem all over just look it up on the internet, don't know why this is not a recall, it is very dangerous. I was traveling 70 mph in the fast lane on a major highway and the car just stalled, also stalled at a red light, also stalled traveling at about 10 mph and at 30 mph (almost rear-ended on both occasions). Chevy does not have an answer, chevy mechanic told me this has been a common problem with all gm cars for years. Why is this not known to the public? they replaced the thermostat and it stalled about a mile down the road. Now they will try replacing the crankshaft position sensor but will not guarantee that this will solve the problem. Next they would try the mass air sensor. This is a known common problem that could be catastrophic if it happened at the wrong time. I know, I was almost killed on that major highway that day.
