You're cycling off of your limit switch.

Put one lead of your meter on the wire that sends signal from W on the thermostat the other on common. You should read 24 volts while the valve is energized. If you're breaking W before the stat ends the call for heat, you're going off on one of the flame roll out switches or the limit switch. If you still have 24 volts at the valve and the gas shuts off, you're main valve solenoid is bad and the valve needs replaced.
