So I have a 95 ram 1500 with the 3.9l v6. Have issues where it will drive perfectly for maybe 10 miles but once it warms up this weird thing happens where you'll have your foot on the peddle but you'll feel a power loss and no matter how hard I step in the peddle it doesn't get better. If you wait maybe 5 mins to cool it'll drive maybe another 5 miles but same thing again. I pull over and try to rev it but nothing much but backfire through the intake. Here is all the work I've done to the truck prior. New timing chain and gears, HV oil pump, new lifters, billet aluminum plenum plate, and a tune up just shy of 18k miles ago, new water pump and belt and just changed oil to 20w-50. Any help is appreciated.
Disconnect the front O2 sensor, and see if the problem disappears.
I missed that. I did install a new o2 sesnor when I did the plenum repair. But you think disconnecting it might fix it? Also is it odd that I only have a front o2 sensor?

Someone took out the rear one but the front does most of the work. What brand O2 sensor did you install?
Only one sensor on your truck, that's normal. The bosch sensors suck, and we do not recommend using them. Unplug it, see what happens.
Alright. Won't be able to do it till tomorrow so I'll get back with the information I get. If it doesn't act up with it disconnected what does that tell me?
