After running for about 10 minutes my 2007 135 mercury Verado dies. Sometimes it starts and runs rough and then dies. I have 10% ethanol gas in the tank and think I have water contamination. Does the fuel filter clear out this water. What other problems may create the same symptoms? A week ago it did this while motoring. After several minutes I got it going again and was able to motor home. This time it spits and sputters and keeps dieing.
