mariner 135 flat spot

can anyone help me with a problem on my mariner135. It starts without a problem and revs fine in neutral, however, when it accelerates it has a fllat spot. When the throttle is fully opened it is hesitant to respond and often stalls, especially towards the end of the day. last thing today it wouldn't even rev above 2000.
