Started after Tranny went from N to Park

Drove to the gas station this morning no problem, maybe 1 mile from my house. Got some gas and no start. Lights and tones came on but no crank. Checked battery terminals and no buildup. Went back inside jeep and move auto tranny thru the gears to N and then back to Park. Started right up after that. Sound like the CPS or NSS? Its a 97 with and auto. Thanks.

NSS. Do a search and you'll get plentyu of writeups on removing and cleaning the switch.
