Gets warm then it sputters and bogs down

Have replaced the fuel pump truck runs okay till it gets warm then it sputters and bogs down also replaced the filter and strainer was wondering about a regulator issue.

The truck would run great then just quit or not start back. Found the fuel pump not running checked for power it was okay changed pump filter and strainer truck ran great for about 15 minutes then stopped. Would try to start back but would not.

Pulled the tank again the pump seem to be working parts house suggested replace again did that truck run ago seems to be sluggis after it warms up it sputters like it is not getting enough fuel. Parts suggested a coil
