2014 Ford Focus - won't start, lights, horn, radio, etc work, but engine won't turn over

Car won’t start..no sound when turning key at point that the engine should engage. Few months ago check engine light came on, but car ran fine….then a few weeks later it was like the car wasn’t getting gas…kind of sputtering. I pulled over, reved the engine…turned car off, restarted it, and it ran fine…has done this several times, though the last time, restarting the car did not help at all…it usually does this when the car is first started, but has also done it while driving along at 75mph….any clue what this may be? the sputtering was getting worse and I had intended on taking it to garage, but evidently waited one day too late..go out this morning – won’t start…
