Bobcat 873 fuel sucking air?

[mp30]

I have a bobcat 873 that will run great for 10-15 minutes with no issue then it dies like it's sucked air. I have recently changed the fuel filter and the primer bubble. The bubble had a crack in it so I thought that was the problem. After I changed it I ran it for an hour or so and then it started dying again. It has a lift pump on it but it also has an electric fuel pump before the lift pump that I'm assuming isn't factory. Any ideas?

Check the fuel intake tube inside of the fuel tank. These have a habit of cracking and breaking off inside of the tank.
