2013 mercury fourstroke efi loss of power !

[istokbasser12.5]

Engine starts great, after a minute or two of acceleration rpm falls and stalls. Engine will start up and do the same again. Primer bulb will suck half flat. I have made sure the tank is vented. I have replaced the fuel line, to no avail. There is a check valve built in to the fuel line on the remote tank. could this be the problem ? Or maybe a new fuel filter. This outboard has only about 20 hours of use. Hoping someone can help me before I contact the dealer.

have you replaced the primer bulb too ? if you have, have you tried just hooking your fuel like to a portable tank ?
