One of the best tooling investments you can make - especially living in a cold climate - is a 50.00 load tester. As the no start occurs at a certain low temperature - that's where you want to load test it. Driving it to Advance will have the underhood nice and warm, the battery nice and warm and it may pass load then - but at 20 in the morning fails. The amperage a battery delivers goes down with temperature decreases!

An old diesel mechanic taught me a trick. Load test from the starter lug instead of the battery term (shorten time of test to ~5 seconds). That tests the cable. If you have a cable end that allows moisture up the cable - it becomes ice.

However - it started in N so I don't think its the battery. Cold can effect switches, battery connections etc. - and your neutral safety switch can be on the edge - coupled with the lower delivery of a cold battery... computer sees low voltage and does not engage tip start.
