This happened to my 2001 Regal... There is a factory recall on the Catalytic Converter going bad. I had mine replaced with the recall and haven't had a problem since

most likely it is not actually a misfire it is the overdrive/TCC solenoid kicking on and off, it is a common GM transmission issue

SOURCE: car starts and runs fine then dies

ya could be a bad filter. or maybe your injectors are getting bad.

unfortunatly it sounds like you are having issues with the torque converter. it sounds like it is locking up all the time now. this requires the transmission to be taken out to change it i do not know what your experience is so not sure if you have the tools or knowledge to do it yourself.
