Hello,
I've asked a question on multiple forums a few times, so let me make this the best post out of all of them...
Recently, I bought a 1994 Dodge Dakota 3.9l v6 with 78,000 miles on it. About every ~60 miles, it seems to lose power while I'm driving. I'm not exactly sure what the correct term is here, but I'll give a better explanation:
This happens when the truck is either cold or warm.
Could happen 3 miles after the last time it happened... or 150 miles after.
It idles fine while this is happening.
When I try to put more power into the throttle, the less power I have.
When trying to put more power into the throttle, I can hear a popping sound every few seconds, which is presumably a backfire.
If I put the truck in neutral while driving (if this happens on a highway or something), and turn it off and restart it, it's fine for another 60 miles.

Now, I'll tell you what I've replaced:
Throttle Position Sensor
Crankshaft Position Sensor
Camshaft Position Sensor (Pickup Coil)
Ignition Coil
Spark Plugs
Catalytic Converter
Distributor Rotor/Cap
Idle Air Control Valve
I'm probably forgetting something, but I think that I covered most of what I've done.

- I have an ECU on order to see if that'll help any of my issues, but that comes in a day or two.

If it's worth mentioning, the truck idles a little rough and I can feel a slight bounce when at a stoplight or similar. The tachometer shows only 400 when idling, but when I plugged in my scan tool, it is idling at 670-700, but jumping around. Also, the stock radio sometimes has an issue where it won't work for the first two clicks of the volume, but will then get super loud on the third click, and it will be super staticky.

Thanks for your time!

Split/leak in turbo hose?

To be honest with the time and money you've spent replacing everything, you could have probably had it to a decent garage for analysis.

The fault on the radio will not be related.
 
A basic question , so forgive me . Is your fuel filter and air filter clean? It sounds like fuel starvation to me.
Or as @DPG said an air leak/mixture problem.

PS. Maybe dirty fuel or corroded tank.
