Boat: 2006 Four Winns Horizon 210
Engine: 2006 Volvo Penta GXi-F
EFI engine

Outdrive: SX-M 1.60

Problem:
I noticed an intermittent whine coming from the engine that would go away before I could figure out where it was coming from. At first I thought it might be a bearing on a pulley going out as it would wind up and then down and go away. The following week it came back and was louder and after going through a couple of wind up/wind down cycles the engine sputtered out during the whining. The engine fired right back up without hesitation and ran for a while until the whine came up and it sputtered. Nursed it back to the dock. The engine always fired right back up without hesitation. The sputtering and dying would happen under throttle and at idle.
Usage:
I trailer my boat and have to use 10% ethanol fuel as that is all that is sold near me.
Troubleshooting so far:
I have seen that this is probably a fuel pump issue or blockage issue. I am slowly getting better at the mechanical fixes but need some help. I have changed out the fuel filter and did not notice it to be dirty fuel or notice any water separation. I hooked up a fuel pressure gauge to the shrader valve on the fuel assembly. I had about 62psi when key turned and 80psi when engine running. After running the engine for a few minutes on the muffs the whine started and the fuel pressure dropped down to 40psi and then to 20psi and the engine started sputtering and died.
Possible solutions????
I am contemplating buying a new fuel pump assembly as I do not want to just by the high pressure pump just to have to repurchase it and get the whole assembly (would not sit well with the wife!).
Question?
Any thoughts on if this is the right way to go to replace it, I have read that the pump is not serviceable and/or I may not be competent enough to service it.
