random check engine light and engine bogs

[Ranger Sport Honduras]

how u doing fellas?
im having a bit of trouble with my 2.5,
the check engine light comes ON randomly, but i noticed it goes OFF when the fuel tank is at half or 3/4 full, once it starts going empty, like under half tank the CEL comes ON, is this something with the tank vapor controls?

Also sometimes, not too often im driving like usual 45-50 mph in 5th gear or any gear on any speed and the engine just bogs like if its out of gas, does it for some seconds and suddenly backs to normal, this happens while driving or while starting to drive. When this happens the CEL does not comes ON.

when i got the truck it suddenly died, turned out the fuel pump was dead, replaced it with a new pump and also did a mayor tune-up, cleanded inyectors,replaced spark plugs, wires, filters, timing belt.

is there a chance that a fuel line is causing this?
when the pum was replaced a fuel line was replaced too, thats why im thinking that could be the problem
thanks in advance
