1994 90HP Evinrude Won't Idle

[GetHooked]

In August of 2015 I made a 17mile run to a popular Perch fishing area. On the way down the lake the Motor ran fine like always. After ready to leave our 1st fishing spot the Motor didn't want to start. We could smell gas so we waited a few minutes and then it started but after shifting into gear I had to quickly keep the RPM's up to keep it running. At the next 2 fishing spots it was the same thing, but did not smell any gas. We ran the 17miles back to home Port and Motor purred like a kitten like always. When we got back to the Marina we had to wait for a Boat to get out at the Ramp. The Motor conked out in idle. We paddled into the dock and a few days later I replaced the Plugs and Fuel Filter. After hooking it up with the Rabbit ears for water it fired up but with the same problem of not idling but runs with the RPM's up.

Please advise if this could be a Coil Problem. The Motor is a 1994 90HP Evinrude E90TLERC
