Stalling Car

Strange issue. We have a car we mainly use for traveling ranging from weekly to 3 weeks apart. Mostly it is trips greater than 100 miles. Never trouble starting but 5-10 miles out of town it cuts off. We thought and repair shop determined it was a corroded battery cable. It has always restarted after coasting to the side of the road and working on the cable. It did it again this weekend right out of town two weeks after being repaired. It is also a one time thing, does not happen further out in the same trip, even a 4 day, 600 mile trip. Any thoughts appreciated.

I hope that the repair shop would have but when it stalls, it does not show anything on the dash board, it really just shuts down, no radio. Just thought of it but luckily it has always been in the day, about 5 times, only once after the corrosion was fixed.

no radio how about other dash lights. still would re check all cables for any that may be loose besides the battery there may be one near the under hood fuse box. gm also used 2 positive battery cables at one point at the battery if one lost connection it would cause the vehicle to die.

In regards to dash lights, they do come back on. It is rather quickly, also the car shows that the vehicle is in "Park" although we are coasting down the road. We do have two positive lines to the battery. Could it just be a coincidence that it does not happen again later in the trip, even the next day on the same trip.

If the vehicle starts after stalling, it is not a battery problem. It also indicates the battery cables are not likely suspect since the amps flowing through the battery and cables during starting is the largest load on these items. This does not eliminate the second positive battery cable if it is not part of the starting circuit. The only other possible item I can think of is the alternator. If its output voltage (engine running) temporarily drops to less than the battery, the battery is not being charged and there may be electronics that become reverse biased and stop functioning like the ignition. Once the engine stalls, there is no alternator voltage and the reverse bias condition is gone. Things go back to normal until the alternator voltage drops again. Verify the alternator has the correct rating for your vehicle. Second, take it to an auto parts store and have it tested for output voltage and current. Hope this helps.

There is infamous ground cable that causes stalls on those cars. If you pop the hood open and face driver side of the engine bay, it will be down at the bottom somewhere close to the steering link. You should see it with flashlight. It connects to the firewall and then to the engine. Engine end of it tends to loosen up or, simply, rip, as engine moves on mounts and it is, also, exposed to the elements from underneath. Start there. GM powertrains have all kinds of ground cables issues.
