Natural gas furnace stops after 10 minutes.

I have a Trane Furnace TUE080A948b0. From a heating standpoint, it runs as it should, but for only 10 minutes (95% of the time). Every once in a while it will run longer until the Thermostat conditions are met, but the majority of the time it only runs 10 minutes.
It is not the Thermostat, as I've removed that and jumped the call for heat wires, and the Furnace still shuts off after 10 minutes.
Obviously all the initial conditions are met for it to initially work (inducer motor, igniter, limit switch, pressure switch, gas valve, and radiant heat sensor).
I would like to note that while the Thermostat is single stage, it looks like based on a furnace timer, that the Furnace goes to its second stage around the 10 minute mark....not sure if this has something to do with it. I don't know what conditions would change that would prevent it from going to second stage.
The furnace always starts 100% of the time with heat, after a reset or new call for heat, but shuts of at around 10 minutes.
Any ideas?

Welcome to the forums.

Does the entire unit shut off or does the burner shutdown and the fan continues to run ??
