2.5l bogs down at highway speeds

I have a 1995 wrangler and after cruising highway speeds for a wile (25-30 miles) it will bog down. I will start losing speed and after a few minutes the will just sputter once in a wile. I took a trip to the beach a few weeks ago and on the way home (45miles) the last 7 miles did this. For the last mile the check engine light came on. When I got home and killed it the light never came back on. What could it be?

I just noticed this is broke in half. Looks like a vacuum line that is located at the very front of the fuel rail. It goes down to the intake manifold under the throttle body.

How old is the catilytic converter? Sounds like classic clogged cat symptoms.

Could be a clogged cat like said above but thats just going to cause constant back pressure in the system you would notice a sluggish feel all of the time, and a higher idle. It sounds like more of a fuel issue, pump might be going bad not allowing the high flow need at higher speeds, Not sure about the van line but would fix that before trying anything else.

That vacuum line looks to be leading to your pressure regulator, with no manifold vacuum your regulator is supplying fuel pressure for WOT get that fixed and your problem may disappear
