Hey Cort==The a/c compressor draws about 10 horsepower. At idle your engine is developing about 30 hp so you are taking about 1/3 of it for the compressor. You may have switch problems on the compressor causing it not to work in some positions. GoodluckJoe
Clean the battery cables first.
Pressure Sounds was created in 1994.
Do not run the engine until you have checked oil level, sounds like you are very low on oil.
Audi A4 1999 1.9TDi Oil pressure light on continously. Engine sounds fine. How do I remove electrical connector to remove switch and check pressure with a gauge?
It sounds like the fuel pressure is bleeding off thus not enough pressure to open the injectors. After a couple of tries the fuel pump rebuilds the pressure and the engine will then run.
Check the fuel filter and the fuel pump pressure. The problem sounds like the fuel pressure is too low to keep the engine running.
This sounds like there is low or no oil pressure.Best to have oil pressure tested with a mechanical gauge.Running a engine with low or no oil pressure will cause major damage to it.
Korotkoff sounds are the sounds heard when measuring blood pressure using a sphygmomanometer. They are produced by the turbulence of blood flow in the brachial artery when the cuff pressure is gradually decreased below the systolic pressure. These sounds correspond to the systolic and diastolic blood pressure readings.

If you have the correct weight oil in the engine, it sounds like the engine may be worn. If you haven't checked the oil pressure with a manual gauge (vs the dash gauge) that is a good place to start to verify that it is not a gauge/sensor problem.
Composing.
Sounds like your cigar lighter fuse is blown, located in the front fuse box under the engine hood, should be a 10 or 15 amp fuse
