Narrative:

[In cruise flight at 4;500 ft I] heard engine sputter. [I] increased mixture and added power. Engine seemed to have stopped. Contacted [ATC] and informed them I believed I ran out of fuel and would be making an emergency landing and asked what my options were. [ATC] informed me [nearest airport] was 19 miles away and I replied unable. I looked for roads as possible landing locations and all had power lines on one or both sides. Another aircraft offered to come and assist; but they were 30 miles away. I found a field and informed [ATC] that I would be landing in it. I received no reply but heard the other aircraft attempt to make contact with them. I followed appropriate actions to make the soft field landing and once the airplane came to a stop; I radioed over [ATC frequency] that if anyone could hear me; I was okay and abandoning the airplane. I then called my flight instructor.
