Hello, My name is Lee and I have a 2007 Mercury 115EFI Serial # 1B475550. I'm having a issue with loss of power. When I start it up it runs fine, then when I run it across the lake for about 5 min it just looses power like I'm bringing the throttle back. I bring it back to idle and the whole motor shakes and shuts down. I try to start it back up but it just shakes and shutsdown again. I recently had the main fuel pump replaced about a week ago due to the fuel pressure being low reading about 20PSI which should read about 40PSI. I took it out this weekend and it's still doing the same thing.

Could someone help me out that may know what is going on?

Thanks

Lee
