I know it's only 10 years old but....

Engine dies at idle.
RPM drops to 2-300 and then it dies.
Turn switch on to start.....nothing.
Switch again started fine. Clock set back to 12:00
Battery checks good at Pep Boys.
Alternator putting out 12-14v
Truck runs fine above idle.
2003 GMC V8 Small block.
Suspect an electrical switch gone south, but where to look????

Any help would be appreciated.
