check oil pressure gauge went on yesterday and truck stalled. on 2002 Chevrolet Silverado 1500

about a hour later we went back and i could turn the truck back on but still had the check oil pressure gauge on. could it just be because it was -15 with the wind chill and oil was to thick or you think it can be the oil pressure switch

Something is wrong unless your using 90w oil. Best get that checked out asap.
