Possible Fuel Jelling Problem

I have a BX23S and it exhibits some fuel problems occasionally.

Last year, I was plowing the snow from our driveway and everything was 100% for a while. Then, it started what I can only describe as an out-of-fuel condition - the engine started missing and the rpm would drop, then recover and drop again until the engine finally quit. There was lots of fuel on board so I thought that my lift pump had failed. I replaced the pump and everything went back to normal so I thought I had nailed the culprit.

This year, I had two incidents. In the first one, the symptoms were exactly the same as last year. But, it was colder than normal so I thought I may have a fuel jelling issue. I added some anti-jell to the fuel and everything went back to normal and I was able to finish plowing the driveway. That was a few weeks ago. Yesterday, I was back plowing again and the same thing happened with exactly the same symptoms. But, I was running treated fuel so jelling should not have been an issue. The tractor was now blocking the driveway and I wasn't sure what the problem was. So, I decided it was time for a coffee. After I had my coffee and played on the internet for a bit, I went back out primarily to see if I could figure out how to get the tractor out of the driveway without power. Just for the halibut, I decided to try to start it. It fired up right away and I was able to finish plowing the driveway.

So, what is the problem here? I can't see it being jelled fuel because I was running treated fuel and, after it quit, I didn't do anything to it. I just let it sit for about an hour and it self rectified the issue. Why would jelled fuel un-jell itself? If this isn't a jelled fuel issue, what else could it be?

TIA

It could be an obstruction in the fuel lines.
Thanks, I hadn't thought of that. But, if it is an obstruction, why did it run properly for so long and then quit? Then, why did it start and run after sitting for a bit? I would think that if there is an obstruction, the problem would be constant until I cleaned out the fuel line. Am I missing something?

You probably have something floating around in the tank that intermittently plugs the tank outlet. After the tractor sets, it floats away from the outlet.

Other possibility is that the air filter is getting snow in it.
