POWER LOSS

1990 GMC S15

Computer problem
1990 GMC S15 6 cyl Four Wheel Drive Manual 170000 miles

Okay,

So the truck started off well but now the issue is severe power loss on any longitudinal grade. I'm thinking spark fuel or air. So, fuel pump, blocked cat, or maybe, plugs wire? Well, I'll keep trying.
