A couple things could be going on.

First, you could have a leak and NOT know it. On our previous travel trailer I had a propane tank that ran out of propane, even when it was shut off. It did this for 5 years. I never, never smelled gas. I tried the soap bubble test on everything multiple times, and when we traded the trailer, that tank went with the trailer. I told the dealer about it, he said no problem changing the value for the trade.

So, it's possible you have a leak somewhere and just can't find it yet.

Second. On other forum posts where a similar occurrence would a happen, I always made the suggestion that the regulator, or the gas line near the regulator is simply frozen because of the cold weather. I've been criticized sharply by more knowledgeable people who say that can NEVER happen simply because of the very nature of the gas.

Yet, I have seen and experienced first hand, on many occasions, where city gas lines coming into houses (and churches) have frozen causing the gas flow to stop.

The last time I witnessed this was some time ago when the outside temps in Central Indiana dropped to around zero and below. We were going to Sunday night services and about 10 of the men of the church were all huddled around the outside of the building. They had built a temporary, make shift shelter out of plywood and tarp and had heaters blowing on the gas meter and regulator. One more cook in the kitchen would have not have helped anything, especially since they all had everything under control, so I just stood back and watched, I helped take my turn monitoring the heaters, and we all cycled back and forth between freezing out side and reviving with coffee and hot chocolate.

Then, even last winter, we were in Northern Alabama when temps dropped below freezing for a few day and several folks started having problems with their furnaces and were outside with blow hair dryers blowing heat on their regulators.

So, no one will ever tell me that that the gas pressure regulator on your propane tanks are not affected by cold and will "never" freeze up.

The third possibility is, because of the cold, the pressure inside the tank simply dropped. It might be completely full of propane, but in the cold, the pressure dropped enough it doesn't have enough "umph" right now to run the appliances in the trailer. Think in terms of how pressure changes in your automobile tires. When it's cold, they can drop 5 or 10 pounds. Doing nothing to them, if it heats up to 100 degrees, they may be 5 or 10 pounds over pressure. (Maybe not that extreme, but you know what I mean.)

I do know from using BBQ grills with propane tanks, when it's zero degrees outside, they don't work very well.
