WHY won't my 1996 Chrysler Sebring run then just quits running for no reason about three months ago i replaced the crank pos switch?

I had the same problem 3 times on my '97 Sebring. Twice, I replaced the crank position sensor with the (lower-priced) after-market sensors. They worked for a while, about a year and they go bad again. Finally, I replaced it with a Chrysler part, and have had no problem since. I hate to say it... but for the difference in price, this is one part I would highly recommend spending the extra money.
