Hi Folks,

Trying to diagnose my 1996 Mercury EFT (Nitro Series). Has run well up until about two weeks ago. Sporatic cutting out (total power loss) at varying RMP. Doesn't always kill the engine and usually comes with a beep although I don't know if it is always.

Seems to be getting more frequent. Sounds like a huge labor issue at the shop. I would like to try some DIY fixes first. Any ideas? Fuel Pump? Oil sending? Sensor? Thanks for any help.
