95 dodge diesel 2500 12v. fass fuel system. This is my little cousins truck. It runs just fine then all of a sudden it feels like its running out of fuel. I test drove it 3 times and it didnt do it to me. Last night I traded him vehicles because the 95 stalled and would not start again. I let it sit about 10 minutes and it fired right up. About 1 mile later it did it. Now when I felt it losing power I brought the rpms up and it leveled out in about 30 seconds.. Any advice. Thanks guys ahead of time

 

Sound like it's sucking air. Check the fuel lines, hoses, o-ring on filter housing, ect.

 

I agree with above^^^^^ sounds like air leakage but also check for any hoses that are weak because when I had my fass in I turned the pressure up on it (variable pressure pump) and it sucked a hose flat. The old hoses especially if you have used biodiesel dont hold up under pressure or suction too well.
