Small Engines (Lawn Mowers, etc.): Snapper s31sst weedeater, walbro carburetor, snapper s31sst

Question
I have a snapper s31sst weed eater. Recently I had to take it down to replace the metal rewind spring. When reassembling I replace the fuel lines and noticed it had a Walbro carburetor. After fully reassembling, it cranked up and I used it hard for about 30-45 minutes with no problem. Then it just died. I refilled the gas tank and it ran about 10 minutes and died again. Finally all I could get to do was just crank for a second and it would die. Do you have any idea what might be causing this to happen?  Any help or advice you can give, I will certainly appreciate.  Thanks

Some where the is a leak causing the engine not to keep a steady flow,did you install the fuel lines back the way they came off? If they are wrong it will cause that type of problem. Recheck all the lines and the gaskets somewhere there is a leak.
