My 92 Buick Century 6 cyl, fuel inj, idles fine, accelerates fine, but stalls after it warms up while driving down the road. Sometimes it will start right back up and other times I might have to wait 5-10 min. I changed the fuel filter with no change in problem. I know a lot of other owners have the same problem. Is there a common cause for this phenomenon? My brother seems to think it is caused by a bad coil in the coil pack that gets worse as the coil gets warmer. Any ideas?

It could have to do with a coil. However, has the check engine light come on? Have you checked fuel pump pressure? Does this happen often or does it run well most of the time?

The problem happened once on the first day then quickly got worse in the next couple of days to the point where it would stall out 3 times when going a distance of 5 miles. I never noticed the check engine light coming on. Sometimes, when going about 40 m.P.H, the engine would stall, all the engine lights on the dash would light up, and just as quickly, the engine would start and everything would appear normal until it would stall again.
Other times the engine would stall when going just 20 m.P.H and not start again until I would wait for 5-10 min. When I replaced the fuel filter the engine started immediately after I turned the key even though a lot of the gas had drained from the line. Of, course the engine was cold. Would a fuel pump problem get worse as the car/pump warmed up?

I would check the fuel pressure. THe fuel pump can go all at once, or it could go slowly. Here is a how to for checking fuel pressure:

You'll need a gauge, but most parts stores will lend or rent one.

Let me kno what you find.

I finally took this car to a mechanic. He let it run for about a half hour like I did. It stalled out for him but started right up so, he could not get any diagnostic codes. He started wiggling sensor wires. When he wiggled the crankcase sensor wire, the car stalled. He replaced the sensor and so far, so good but, its only been a couple of days.
