New ignition switch solved this problem plus others such as cruise control.

About cruise control-- I do think it is somehow connected to the electric problems. Also, it seems that when I remotely start the Cobalt, the fan quits but unsure. It didn't work for days until one morning I start the car via the key in ignition and the fan worked. Seems like a consensus and I should replace the ignition start switch but may be a different part number for the Cobalt. Thanks so much.

The cruise control leads could also run through the ignition switch. When you see the wiring harness for that switch you can see that it handles many connections. When the switch goes bad, everytime you use it there is a chance for a connection to open up or reconnect so the problems appear to be random.
