Last Sunday I pulled it apart, gave it a good cleaning like I do every few months. Last night I came home from work and it wasn't running. Pulled everything apart, gave everything a good look over reassemble and it started to work again. Then this morning while I was sitting down having breakfast I heard it stopped working. Again, polled everything apart, inspected everything, lubricated the shaft with a little bit of ptfe grease and put it all together. It ran for 5 minutes and then stopped. So i turned the switch off. Came home tonight just minutes ago, flip the switch and it started to run again. These stock pumps are Italian made junk.
