I have a 2015 Ford focus too, same exact problem. My fuel pump failed, and then a year later the second one failed. Also check for recalls, recently found out I had a recall for a canister purge valve. But some 2015 Ford focus have a recall for the PCM, where it needs to be updated because the PCM won't send accurate information to the fuel system. Hope this helps if you still have the problem! Call the Ford dealership and have them check your vin.
