I appear to have what might be two issues with my LS XR4040H tractor. It sat all winter on a battery tender and full of diesel. When I tried to run it the past couple of days , it would initially start up and run for a while. Then it would just quit like it was not getting its fuel. It would restart a couple of times only to immediately quit. After a few such attempts, the key would not even turn the engine over in an attempt to start. Was just dead. I let it sit overnight and the exact same experience this morning. Initially starts and runs for about 20 minutes, then dies with the same issues as cited above.
