Sometimes when I put the turn signal on either left or right (doesn't matter) the car shuts off. Doesn't matter if I am driving down the road or sitting still. Just barely hitting the turn signal switch causes it to start to shut down. Any ideas would be appreciated. It happened this morning and to clear it I had to start the car with the turn signal ON and it didn't happen again the rest of the ride to work. About 50 miles.

From what I've been told, the late 90s and up GM cars have the main steering column wiring harness bundled. It runs down the steering column, into the engine bay, and under the battery. Take a look at the area around the battery to see if it is leaking. If the battery is leaking, the fluid is both corrosive and conductive. If it leaks onto the harness, it may have eaten the wire jacketing on the harness wires. In that harness will be the wires for both your turn signals and your ignition switch. If they're shorted together, when you activate the turn signals, you may be killing the ignition.
