This sounds like a fuel pressure issue even though you put a pump in it I think we need to start with checking the pressure. I just had another vehicle not long ago that was doing this exact thing and they found the pressure low and replaced the pump again. Which fixed the vehicle.

Here is a guide that will help with that:

Once we confirm the fuel pressure is okay, we can move onto a possible ignition issue. However, I suspect this is a fuel issue as the sputtering is common of fuel issues.
