I have a '92 Buick LeSabre that stalls on me at random. Sounds similar to this problem.

Car starts and idles fine, and will sit and idle for hours, perfectly fine except for a bit rough idle.

when I drive it, I can go for maybe 15-20 mins and then it will just stall. Sometimes she starts right back up, and other times it takes mins, even hours. I had it to our local mechanic, and he changed a CAM sensor, which seemed to fix the problem for about 2 weeks, then the problem started happening again. (he put a used sensor in)

brought the car back to the same mechanic, and he let it sit and idel and nothing happened for him...after i explained that it doesnt happen when the car idles, only while driving. He had it for a week and didnt do a single thing to it because the problem didnt occur for him....guess he didnt have a code scanner?!? =/

anyway, i have the stalling when warm problem, and also now my tranny will slip once the car gets warm, speedometer stops working, and check engine light comes on. fluid is good. what do i do?! please help!!! this has been killing me for the past 2 months!!!
