Losing RPM's

So I have a little 9.9 Mercury on the back of our dingy and recently I changed the gear oil, spark plugs, and thermostat (within the last 3 weeks). Yesterday I was out with the wife running near top speed (not all the way) with fairly minimal waves (1-2') and suddenly I start losing RPM.

Naturally I slow down and the engine seems to maintain a low speed (which is good to get my pregnant wife to the boat) but everytime I would try to get the RPM's back up it would start to die. Any suggestions on where the gremlins might be located?

Thanks for the input,
Mike

Carburetor, fuel filter.

Thanks Rick!

Replaced the fuel filter, haven't looked at the carburetor yet. Will do that tonight.
