That is the fuel pump. It feeds the fuel into the carburetor. I would take off the fuel bowl and see if there is any water in it. (1/2 in socket will work) Also you can take the line that goes to the carburetor off at the fuel pump and turn the engine over a couple of times and see if the fuel pump is working correctly. (shooting fuel out as the engine turns over) If the fuel pump is working ok, then I would suggest that the problem is with the carburetor.
If you find water in the fuel bowl, then there is most likely water in your fuel tank as well. Wal-Mart sells HEET, which will help to remove and burn the water from the fuel system. It may pop and sputter as the water goes into the engine. But keep fresh fuel handy and you can run the engine close you your house at full throttle and choke the engine if it starts to die, and run it until the fuel tank is dry. Then you can add the fresh fuel into the fuel tank ( I would add some more HEET to the fuel to help remove all of the water). Your engine should run like normal again.
IF you do not have any water in the fuel bowl and you have a couple of wires running to the bottom of the carburetor, then it could be the fuel solenoid is acting up and needs to be replaced.
If that is the case you will need the MODEL, TYPE, and CODE off of the OHV cover. It is stamped into the metal.
I hope this helps to answer your question.

Why will lawn mower not keep running?

I would say you probably need to clean or change your plug. And maybe even change your oil/gas mixture. Try some carb cleaner also. It's probably a simple problem to get it running normally again.
Also...if a lawn mower is getting clogged with too much grass, it can stall out on you. Don't try to cut too much off at once, if you've let it get overgrown. Cut off only a couple of inches at a time. Which means, you may have to cut your lawn several times to get it where you want it..You'll also have less chance of ruining your lawn by cutting it this way too. Plus, no more tumbleweed laying on your lawn when your done cutting it.

I would check the big three first of all. Spark, compression and fuel. Sounds like you have spark and fuel. I would get a compression tester to check actual amount of compression. If all three of those things are good I would check valve lash. You will need make, model and serial number of engine. If you post these I can help find specs for you. Good luck.

Sounds like dirt or water in your fuel system. Have you drained the bowl on the bottom of the carburator? There is a small bolt on the bottom of the bowl; be careful not to over tighten it. If you find anything but fuel in the bowl you may need to drain your tank as well.

The pump is not good,to test it,you take out the out fuel pipe start the engine ,see if fuel is coming out fully to the pipe,if sometimes it comes and cut,this means the fuel pump is not working properly.You have to change it.
