The clue I seized was the temp change. The same thing happened to me. There was moisture in the fuel system, enough to freeze when the temp descended, cutting off fuel to the engine. I put a can of dry gas in, bounced the car up and down, let it sit and it started. Dry gas [I learned on this forum] is 99.9% alchol. Don't try rubbing alcohol that is 72% or even 90% because the other 10% is water. Spring for the real item sold at auto supply stores.
