P0340 - Camshaft Position Sensor Circuit Malfunction
That code isn't real descriptive.
When you have an engine problem we really need to know which engine you have. On those that use a distributor, that's where you'll find the camshaft position sensor. That's why there's so many wires plugged into it.
You also didn't say the order these things happened. Did you lose power before or after the distributor was replaced? If it was before, the problem may be solved with the new distributor. If it was after, it is likely related to the new distributor, but why was it replaced? Camshaft position sensors and crankshaft position sensors often fail by becoming intermittent, especially when the engine gets hot, and they'll work again after they cool down.
The cam sensor synchronizes the timing of the injectors. Some engines stall when it fails. Some go into backup strategy where the injectors fire based on the crankshaft position sensor. The timing isn't right but at least they deliver some fuel to the engine.
