The moan is caused by the air bags that lift up the car. As they age, they may get a very small leak and it takes a minute for them to rise the car. It usually stops when it has risen. It is only then that I move my car into reverse or drive.
what would cause my car to run fine when it has first started up then after a while first gear will kinda bog down.

Possibly, but which wires? It is unlikely, though. Crossed wires would be much more likely to prevent your car from starting or from running after it begins to fire rather than cause it to die after it is started up and has gone into "run" mode.
DID you check for a air leak,fuel,ok. Carburator?

No. A bad starter would cause the car not to start.
No, a bad crankshaft sensor would cause the car not to start and run.
