Husqvarna rider 16 hydrostatic articulating mower problem

It will run smoothly most of the time but then suddenly out of bo where will start running like this until it eventually stalls out.
I can then immediately restart it and continue on like nothing happened.

I'm out of ideas

Something in the tank shutting off the flow, fuel pump breaking down and not pumping fuel when hot, fuel line separating internally and shutting off fuel flow, clogged fuel filter, something in the carb restricting fuel flow at times. It is a fuel delivery problem so everything in the fuel system is suspect.

I've replaced the fuel filter and rebuilt the carb so far. Also dropped the tank and emptied it. There was a grass particle inside but it has since been removed but didn't fix the problem.

I'll check in your other suggestions. Thank you for the ideas.
