I would remove the bearing and inspect it closely. It's very important to make sure the bearing is inserted in the proper orientation. Installing it upside down or at an angle will cause issues like you are experienceing. Also make sure that the end of the impeller shaft below the magnet is good and clean and shiny. Some steel wool or a scotch brite pad will help with that. Lastly, check the magnet and make sure it's not spinning or moving on the shaft. Your experience with these pumps is very strange. These pumps tend to be bulletproof with proper maintenance. Also, when the pump dies, it normally will only spin for a second or two and then shut off. Running for a couple minutes leads me to wonder if there is an assembly issue on your end.

Post 2 of this thread show the correct bearing positioning.
