It's fixed,,,,, after checking the gas tank I found a fuel filter in the bottom of the tank that was callapsed and dirty so I thought for sure this was my problem . I cleaned it and put it back in the outlet at the bottom of the fuel tank. I put it all back together and started it up and after running for about 40 seconds it shut off just as before, I couldn't beleve it so I decided to clean the fuel line that goes from the botton of fuel tank to carb and cleaned it and that was the problem as I got either red rust or red dirt out of the line so I blew out the carb and put it back on and started it up and now it runs good . Thanks a lot to you all for your help , I really appreciate it.
