I am happy to have found this blog. The description of the problem is exactly what my machine is doing. I have checked the entire charging system and it is fine. I have serviced the machine and it is all fine. I was about to check the fuel pressure when I broke the elbow at the top of the pump. I have ordered a new elbow and will check the fuel pressure when I get it installed. I will update this blog after I have some results.
The fuel pressure was about 22 lbs. The manual says it should be about 43 lbs. I installed a new pump and the pressure now reads about 42 lbs. The machine now starts and operates like new.
