I have a 2010 mercury 60hp four stroke efi. Starts and idles great. Maybe a little shaky, but would prolly idle til it ran out of fuel if i let it.when i open it up It runs great for about 1-2 minutes then suddenly bogs down hard and engine will die if i dont pull back on the throttle. When i pull back it continues to idle. After this happens its pretty much impossible to give it any throttle or it wants to shut off. It is not going into guardian mode. Tell tale is pissing a good stream and the water pump was replaced on it earlier this summer. I already replaced both fuel filters and the primer bulb hose assembly. Still doing the same thing. Any input or outcome of similar experience is greatly appreciated. Also, when it is idling and i leave it in nuetral and pull up on the choke lever on my ignition it will increase rpms and seems like theres no issue at all. Im lost. Please help! Thanks in advance!
 
Sounds like a fuel supply issue. The EFI models need fuel under high pressure supplied to the injectors.
Measure the fuel pressure at the rail

Definitely is starved for fuel. Already cleaned out vst and replaced high pressure fuel pump. My next step is check the pick up tube in the fuel tank and the anti siphon valve . And replace low pressure fuel sensor. I will check fuel pressure though. Thank you for the input.
