The high-flying Somerset side continued their play-off charge after second-half goals from James Hayter, Nathan Ralph and Paddy Madden overturned Chris Beardsley's first-half opener.
The hosts flew out of the traps and came close to taking the lead from a number of early chances, with Kevin Dawson, Hayter and in-form Madden all spurning attempts.
However, against the run of play, striker Beardsley silenced the Huish Park faithful on the half-hour mark with a crisp right-footed finish.
Yeovil continued to press before the break with Ed Upson's curling 25-yard effort dropping narrowly over before Madden did have the ball in the net - only to be ruled out for offside.
Beardsley came within inches of doubling his side's lead with a glancing header in the second half before Hayter expertly flicked home Madden's driven cross to draw level in the 73rd minute.
Seven minutes later, substitute Ralph slammed home his first senior goal from close range before Madden notched his ninth goal in six games to extend the Lilywhites' dire run to seven games without a win.
