I have a 5.7 liter 350. it is rebuilt. the engine runs fine until it warms up. once it's warmed up and i rev it up to 1000 rpms it tries to stall out. i've had it checked for vacuum leaks. and i was told they were fixed but i dont know how to check for them.

    it has a new fuel pump on it. Along with a new gas tank and sending unit. i didnt think i needed to check the fuel pressure.

Have you by any chance, monitored fuel pressure from start-up to warm-up point where it will not rev? Would not be uncommon for fuel pump to start acting up, about the same time engine gets warmed up.

    Is this a carbureted version or fuel injected? (Just to confirm.) Has the truck been scanned for codes?

Chugs, acts like it's not getting gas once warmed up. Idle's fine

This problem can be several things. When your engine is cold, your computer is in a "closed loop" and just pretty much keeps the engine running until warmed up. After reaching operation temperature, the computer starts reading all the sensors. If one sensor is not connected or is defective, you will experience performance problems. Most of the time this will turn on the check engine light, but not always. Second is the fuel pump. This too will cause erratic engine problems.

I have a 1994 Dodge Dakota, no power at low rpms

yes it does if it is reading lets say lower than normal that would explain easy start up and stalling later.the coolant temp sensor has two wires .so if your car warms up and your coolant is about 200 degrees your coolant sensor might say 80 degrees .access to a scanner to check temp would be great.
