I have a 2019 Kubota L47 backhoe loader with about 280 hours. A couple months ago I had an issue with water in my fuel tank due to condensation. I replaced the fuel filter and bled the system and it started up and ran just fine for a few hours.

It sat for about 3 weeks. I went out this weekend to start it up. It started right up and then conked out in 5 seconds. I repeated this same thing about 5 more times. Each time it started and then stalled out within seconds.
So far I have checked the fuel lines for blockages, replaced fuel filter, bled the fuel system of air, checked fuel pump for proper operation, removed all fuel and replaced with new diesel.

Here is a video of what it is doing: https://youtube.com/shorts/q8Zc4mNLwK4

What am I missing? Any help is greatly appreciated.

My key switch went bad on my b7800 and it would go off as i released the from starting. I guess another thing x ould be the shutdown assembly.

Loosen this purge plug and turn the key on do you get pulsed fuel flow out of it?

An L47 is 100% electronic fuel system, not anything like an old B7800 mechanical fuel system, there is no shut down assembly.
