Keep getting p0132 and p0138 codes. Already replaced a lot of items

Hi, new here. I recently bought a 1999 dodge ram 1500 4x4. I keep having an issue with the acceleration cutting in and out after it has been driven for a while.(20-30 min). I've been reading, watching videos, and talking to all my friends that fix their cars. We still can't figure out my issue. So far I've replaced the tps, map sensor, both O2 sensors, catalytic converter, and camshaft sensor. Where should I look next? Thanks
