You see, this does not impress me:
Checked the battery, and checked OK.
In what way was the battery checked? How much of a load did you put on it -how much current did you get and what did the battery voltage drop to during the test? How old is the battery?
Fact is, these cars do WEIRD s#*t when the battery gets weak. We all here have watched people waste time and money due to a bad battery - sometimes, a battery that "tested good".
"Tested good" means little to me, one clown I knew would short the terminals together and if he "got a healthy spark" he assumed the battery was good. That might have worked in 1966, but not today on a Crossfire or ANY of the newer cars.
My vote is bad battery in the key or the car.
