Preheat oven to 325 and grease 2 loaf pans.
Cream together melted butter, sugar, lemon juice and zest, almond flavor and vanilla extract in a large mixing bowl.
Add the eggs one at a time, allowing each egg to fully incorporate into the mixture before adding another.
Add salt, baking soda, and baking powder to the mixture. Mix well.
Add the flour a ½ cup at a time; mix in entirely between additions.
Fold in the squash and poppy seeds.
Divide the batter between the prepared loaf pans.
Bake for 1 hour, until a toothpick inserted into the loaf comes out clean.
