2008 Suzuki DF50 EFI cutting out

[fastal]

My 2008 50hp Suzuki cuts out at about 2800 rpm. It has less than 100 hours on it and I keep marine stabil in the fuel and it's run very little. I've disconnected the fuel tank and tried running on new gas and replaced the plugs and the water fuel seperator with still the same results. If I run it from an idle to a higher rpm, you can hear it cutting out but a gradual increase to about 3800 is fine. Idles like a champ. Any ideas????

Key word !! "Run very little". Check fuel pressure

Thanks, I'll give it a try. A big question though, why, if it's seldom run, would there be an issue with the fuel pressure???

EFI's have filters that will plug, checking rail and other pressures will tell if and what is restricting.
May have injector screens plugging also

OK thanks, I'll check those out also.
