93 Ford Escort Wagon loses power when trying to accelerate from 60+mph

[abates]

I’ll see if I can check that but here’s some more info. On my way into work today I kept my hand on the shifter so I could feel what the engine was doing when the care starts to shudder. During the shuddering the vibration to my hand felt steady and normal so I don’t think the engine is dying. Unfortunately I think this seems to point towards the clutch?
