Attach the picture using paperclip or tree icon, near typing bar. What does it look like, part of throttle? has paperclip end?

Did you get the picture ? Nothing missing!
Does the carburetor have electric solenoid in it's base? If it does the voltage is dropping, and this solenoid is blocking the fuel passage to cylinder. Charging system may not be keeping up, or battery may be dieing.
No solenoid! So it can't be that. Are blades driven by electric clutch or manually engaged?
With engine off, engage the blade lever and see if the deck belt is tight. It should not change when engine is running, it should always be tight when engaged.
OK> You could have something in fuel tank , blocking the hose out of tank, t carburetor, restricting the fuel flow, enough to cut the power down, but not kill engine. With gravity flow , it does not take much to restrict fuel flow.
The throttle flap has two screws that hod it to the shaft, you remove the two screws, and the throttle shaft then will pull out the top. Al that holds it is the flap in the inner throat See link below, I find no video.
