Riding mower stalls after about 30-45 mins

[TheMFM]

Hello everyone I have an 03 Craftsman LT1000 Model # 917.272922 with a Briggs&Stratton 20.5 2 cyl motor. She will start fine and run great for about 30-45 at full throttle and then she starts to stall as if she is not getting any gas. I have a clear fuel filter and there is gas in the filter. If I engage the Choke about half way she will continue to run, but only with the choke half way on. I changed the oil and filter along with fuel filter, air filter and spark plugs.

Thank you in advance for your help and your Time I appreciate it.

What condition is the fuel line in?
'03 , ten year old .. Could be the fuel line has become a little weak and when it warms up it collapses on itself a little and restricts fuel flow.

tzc123 thanks for the reply I am going to replace all of the fuel lines this weekend and the vacuum hose on the Fuel pump. Lets keep our fingers crossed.

when it starts to die try to open the fuel tank cap and see if it runs better. The vent might be plugged.
