pope hasn't been elected. Assuming you're not sailing the Sistine
Chapel, lets assume the former.
You might check your air filter. Blockage would explain all your
symptoms. Besides, checking cheaps things first is always a good strategy.
I had plenty of experience with clogged fuel filters during the Racor
switcheroo. On a W27, the engine would develop full power, then
gradually lose RPM, and eventually die. Fifteen minutes later, it would
be willing to run again as fuel osmosed through the filter. That
doesn't sound at all like what you've got.
Water in the fuel is highly unlikely unless your Racor is saturated, and
then it would probably kill the engine after destroying the injector pump.
I also could be a dead cylinder due to low compression. A compression
check is also cheap and will probably yield good news, at least from the
