580C Fuel Issue??

Hello all,

I have an issue with my 580C where it runs great for a few seconds or a minute or so, then slowly stops running even at full throttle. It's almost like it's running out of fuel. It just started doing this today after running it for about 4 hours with no issue. 

The odd thing is that when I loosen the cover on the side of the injection pump and let some fuel drain out, then it runs ok for about 2 minutes instead of 10 seconds. It always fires right back up right after it shuts down.

I haven't changed the filters yet, but when I opened the fuel return line at the top of the injection pump, there's fuel squirting out of the pump fitting. I assume this means there's plenty of fuel.

I did bleed the air out of the filters several times.

Would water in the fuel cause this? Or air trapped somewhere in the lines? Or is something in the pump screwed up?

Thank you

I did not find the right solution from the internet
