Rose:
As some have already said, i would look at check valves. Just recently went through this with a 5EK. Sit for 2-3 days(over weekend etc) and it would crank for several seconds and start to fire eratically etc and finally pick itself up, just like it would if out of fuel. Got worse, bothering sitting over night. It was a check valve.

 

check valve in filter base or o-ring on a fuel line fitting at the filter base closes to the cab. just went through this found a split o-ring making it suck air.

 

I had that same problem cahnged check valves ,fuel lines put on a fass fuel system, it was injector o-rings

 

let us know what it was, please...

 

Put treatment in tanks to kill algea its not going to go away. Pull check valve out of fuel pump and filter housing.
