Question: Engine runs roughly when warmed up.

After 5 minutes idle, Temp light comes on, engine sputters, idling roughly. When driving the car, engine losses power, coughs/sputters and Temp light comes on. Tried fuel injector clearner, topped off coolant but problem persists. Engine performace woes began after refueling from about 1/8 tank. A reasonable guess suggests rust/water clogging the fuel filter or line but I'm not a mechanic. In your opinion, what could the problem be?
