Is your vent clear on the fuel tank?

[swalley]

yes sir even took it off and ran it

Things to check,
1 Maybe you have some junk blocking the fuel line in the tank
2 The fuel lines could be collapsing I would replace all of the fuel lines from the tank to the pump
3 It could be vapor locking if some of the insulation on the fuel lines is missing. You can try running it with the side covers off.
4 The fuel pump could be going bad.

Or, maybe a sticky valve when it dies. Does it still have spark?

ok checked lines replaced fuel filter still goes dead after about 15 min have good blue spark however I did notice there was little or no fuel in the filter should it stay full or at least have some in it

Take the filter out and see if it will run. If it does, replace it with a screen style filter. I have seen on some gravity feed motors where there isn't enough natural pressure to push fuel through a filter. The screen style will work fine though.

The 2135 has a pump and the tank is under the seat. One more thing to check is to remove the fuel line from the pump to the carb and then crank it over to see if the pump is pumping.

I had the same problem, it ended up being fuel pump. Engine ran so much better, but I had to re-adjust carb settings. Fuel pumps can cause a lot of problems, I have come to the point when I have carb issues I Replace all fuel lines,rebuild carb/clean, replace filter, check gas cap, and fuel pump last as they are expensive !!
