What is your question?
I've got a little over 150K miles on the truck. It's a 5 speed standard and my daily driver. It runs fine for about 45 mins to an hour, then starts acting like it's skipping. Starts out doing it in only my power band rpms (1500-2000rpms) I've changed out the plugs, wires, cap, rotor, tps, and the cks, cps, and coil 2 years ago, before the issue started. This is seriously starting to irk me and I've had is looked and and even had the local dealer hook it up, but to no avail. HELP!!

Po300 is a misfire code, you have replaced many ignition components and sensors needed for the computer to determine when to "time" spark and fuel. I would start with basics check for a vaccuum leak arround the intake manifold (repair shops have a machine that generates inert smoke it is pumped into the engine to locate leaks), next verify fuel pressure and deliver. look at scantool information (particularly fuel trim, oxygen sensor readings and what the air flow meter readings are) after that I would be suspecting a bad fuel injector, bad wiring/connections or even a computer issue.
I had the same thing happen in my truck and it ended up being a broken exhaust valve. Sounds like this is a common problem that dodge has when they get around 100,000 miles.
autotechpat, I forgot to mention that when I do try to accelerate while it's pulling this crap, sometimes the engine begins to make a loud clicking sound, like a relay snapping shut, not a mechanical sound.
