Truck will run for about a mile and a half and then rpms go down and engine sounds like it's getting no fuel but I just had the pump checked and it is fine. If I restart the truck it runs fine But now the problem returns even quicker because the truck has been running. Idk what the problem is but if any suggestions plz let me know.
