When your engine turns over, there is an oil pump inside the engine that is being driven by the crankshaft. It is creating pressure by pumping oil throughout the engine. Most will achieve around 40 to 50 lbs. If there is a problem with any of the lines or gaskets in the system, it will leak when there is pressure. Try to locate the leak by washing the area that's leaking and watch it as someone turns the engine over. Most leaks of this sort aren't too hard to fix.
The engine turns off when the oil cap is removed because the engine is designed to do so. When the oil cap is removed a vacuum leak is created which causes the engine to turn off.
An oil leak is always going to be out of the engine as the engine contains oil and the car does not. I think you are saying you are loosing oil with no apparent leak. If that is the case the engine is burning oil and that is why you see no leaks.
If you have over filled your engine oil, it will not "leak" unless you have completely filled the engine with oil and is pouring out where you put it in. However overfilling even as much as little as 1 quart can lead to catostophic engine damage as the crankshaft will spin into the oil in the pan causing it to foam and cause oil circulation problems throughout the engine leading to overheating and engine siezing.

Oil pressure as measured by the guage on the dash is usually a measure of the pressure put out by the oil pump and not an indication of a leak or low engine oil level. If you have a leak your best indication of that will be puddles on the ground, on the underside of the engine or a milkiness looking color in the oil (as seen on the dipstick) or in the engine coolant.
