Mine is still having the same issue and with my regular props on that spin to 5000rpms, its happening at 4000-4100rpm and pulls back 200ish rpms.
BTW, I FB messaged with BUP last night and he is pretty sure its my EST module and/or pick up coil going out.

I did buy a new cap, rotor and ignition module for mine to be safe, gojng to run the boat this weekend.
I hooked up a scanner for codes, nothing. I also ran a fuel pump test with the scanner with a fuel pressure gauge on the rail, 48-49 psi while the pump was cycling, held about 44-45 when it was turned off.
