I had a similar degradation of power during one season due to a slowly clogging fuel filter.

The old foam in my fuel cell was deteriorating.My 1/2" line and filter handled that up to a point where I also though: that is not my power.
I also apologize to any passengers in these days.

It pays to chech here frequently as well - I am lucky that I did not lose a piston due to lean conditons.

My next car has a fuel pressure gauge!
