I have replaced spark plugs, wires, spark coils, and had engine checked out by local dealer. Car will be running fine for weks at a time then will randomly stall when driving, no indication of issue prior to stalling. Runs good, smoth idle, good acceleration, no issues we can find. When driving car has stalled at low speed 20mph and at highway speed 65mph. Their is no indication anything is wrong prior to stall, just suddendle the engines off, all electrical still works, just no engine. When this occurs I just put the car in neutral, keep coasting with traffic, and restarts immediately, back into drive and keep going. Has happened 3 times in last 3 months and about 6 times in the last year. I have no clue, and aparently neither does the dealer. Any suggesstions?

I have exactly the same problem with my daughter's 1995 Delta 88 LSS and have tried many of the same fixes. From her description (which is rough at best), it acts like it is temporarily starved for fuel. I'm thinking fuel pump? Not sure. This time I think it threw a code, which I need to pull.

Details of the car:
Supercharged 3.8L 67,000 miles
New plugs, wires, harmonic balancer (the rubber dry-rotted). No major repairs otherwise. Problem occurs about once / month --- stalls for no reason, starts right up afterwards. Originally suspected loose battery terminals / ignition loosing power. Have tightened battery cables, "seems" to work for a month or so.

Had the problem happen again the other day. I had just filled the gas tank and shortly after the engine just stopped again and immediately restarted. It almost seamed that a slug of water went through the system. I wonder if their is a possibility that moisture collects in a location until it reaches a certain level then gets sucked through the fuel line all at once and kills the engine. In thinking back I do not believe I have ever had the engine die during the winter or cold season. Any thoughts? Is their some place in the tank or the fuel system where water could accumlate until it got high enough to suddenly be fed into the injectors?

Have computer checked for trouble codes. An Auto Zone can do this if codes let us know

Borrowed a code reader, no codes stored in the car. Sigh.
