Most likely stuff inyour tank coming down the line. Blow air back to the tank from before the lift pump. This will temporarily clear the blockage..Drain and clean the tank. It happened on my brothers 6060 with 200 hrs on it Tank had crap in it from the factory . Had the same problem with a fairly new Cat telehandler.
Nice
Diesel fuel can grow algae. In wetter areas it can be a problem. Use a marine fuel additive to prevent it from growing. I like seafoam.
