I have a 98 evinrude 225 (E225STLECS). Last week while at the lake the check engine light came on. I shut the motor off and then restart it and it ran for about 10 minutes and the light cam on again. Not sure what could be wrong since the motor is running great. The owners manual says to check the fuel flow but everything seems to be fine. What do I need to look for or should I just take it to the dealer?

Thanks in advance for any assistance.
