[QUOTE="Mama's Lacrosse, post: 360197, member: 60793"] My vote is the cat. If it was a fuel issue it wouldn't slowly lose power it would act like it was completely out or start sputtering. Try some full throttle runs after the engine and cat are up to temp and see if it goes through the whole rev range with out bogging down. If it's the cat you'll notice a problem right away. Just cruising would take longer to make the cat act up. [/QUOTE]
