Cobalt shuts off while driving.

Here is my problem. We put alot of miles on our 2006 LS. It had 8 miles on it may of 06 and now it has over 80,000. My wife drives a lot on her job. But one day a couple months back, we we're driving along about 45 mph and all of a sudden the car just dies. Everything just shut right down: no lights, no gauges, no engine, no sputter, no warning...it just shut right off. We pulled over and it we shut off the key and turning the ignition back on and it started right back up (http://www.automotiveforums.com/vbulletin/showthread.php?t=936132#) and had not a problem...until today. The same thing happen to my wife as she was driving , a complete shut down. Again, no lights or anything. Again she pulled over and turning the key back on and it fired right back up. I hope it left a code as I'm taking it to the dealership saturday. Anyone else have this problem? mark44004@yahoo.com:banghead:

Ignition switches were known to have acted like this in the 05 & 06s.

Seems the "key" was to not have a lot of junk hanging on the key ring(s).
