MYSTERY Sudden loss of power while accelerating

So...I can't say I'm advanced in my automotive mechanical skills, but I know enough to tackle projects w the help of youtube/forums.

I just tackled the replacement of my slave cylinder, everything went swimmingly and while I was down there I took the time to replace the clutch plate and pressure plate as well. Reassembly went well, we had to remove the exhaust and transfer case in the process and those went back into place smoothly.

The clutch feels much better, we remove the master cylinder as well and did a full bleed of the whole system.

Took it for drive, everything seemed fine UNTIL I attempted to accelerate while driving up a hill. Suddenly, there was a loss of power and no to minimal acceleration.

Initially I assumed that the new clutch was slipping and I mustve done something wrong during reassembly. After further observation, I believe it's safe to rule out clutch slippage. The RPM refuses to rise, and the engine itself seems to be losing power under certain load.

I checked MAF - seems clean and working. Checked air filter, seems clean. Them I found a small gash in air intake duct that that been previously repaired but seemed to have opened back up while we were working around it. Sealed that back up and expected the problem to be fixed. Nada.

I can't figure this out!! Any ideas??

Thank you
