Hello, thanks for writing in about your 1997 Ford Ranger! I would replace the fuel pressure relay first since you replaced the pump already. If the problem continues, then you may have to remove the fuel tank completely and remove the fuel pump to look at the bottom of the tank to see if you see a fine grain metal at the bottom. If so, then you may have to replace the fuel pump once more and clean out the entire fuel tank and wash it. Clean and dry it completely. If you need help having this checked, a professional from YourMechanic can come to your car’s site to diagnose your stalling issue and verify what repairs should be made.
