All of a sudden, the engine in my L865 will run for exactly 34 seconds after starting up in the morning and then die. No sputtering or stumbling; it runs perfectly for 34 seconds and then dies as if I shut the key off. I can immediately restart it and it starts and runs perfectly for 34 seconds again and then dies. After I do this about a dozen times the engine runs smoothly from that point on. If I turn it off and then restart it through the course of the day it continues to run fine. If it sits overnight I have to go through the same multiple start cycles to get it to run again. It's sure acting like there's air slowly leaking into the fuel lines. Has anyone had a similar problem? Any idea where to start looking?
