Here we go again. Its acting up worse this time!

Well, yesterday I went out and hit the key and it fired right up. I drove around in the yard for a minute and it didnt stall at all. Then I took it out on the street and it stalled. I had a pretty hard time getting it started again. Then after it started back up, I took it for a 5 mile drive. Ran perfectly fine. Then I shut it off at the store and it did not want to start back up. I got it runnning and came the 5 miles back home.
I ordered a float for the carb so I can get it rebuilt. Should be in next week.
