Question about 1999 Volkswagen Beetle
So if I'm reading your question correctly, your problems started when you had a dead battery and had to compression start your Beetle. Is that right?
Now, presumably, the battery has a charge and you are able to start the car with the starter, but it has no power; so much so that it won't run when you try to put a load on the engine.
Unfortunately, there are a huge number of problems that can cause this kind of behavior. Is your Check Engine light on? If so, it would be extremely helpful if you could get the trouble codes from the On-Board Diagnostics (OBD-II) port.
Otherwise it's going to be a trial and error process to pin down the issue. An engine needs three things to run: air, fuel, and a spark. Since the air and fuel are all computer-controlled on the Beetle (and pretty much every car currently being made), the only thing obvious left to check is the spark.
The only time I've had a similar-sounding problem with my beetle was when one of the two coil packs went out. Since each coil pack handles two cylinders, one of them going out leaves you running with only two pistons. Get some heavy insulated gloves and try pulling the spark plug wires one at a time and see if any particular cylinder is affected. If the source of the problem is a bad coil pack, then pulling the plug wire on two of the cylinders won't have any effect, and pulling the wire on the either of other two will almost certainly kill the engine.
If all four plug wires act the same when you pull one, then it's likely something in the engine management system, and should have an indication in the OBD-II trouble codes. But without more information, it's impossible to figure out what's going on with your Beetle.

i think you should take the car to a local parts house and have them to test the charging system . If the voltage regulator has stuck it could be pulling a constant draw on your battery also check at night to make sure that none of your lights are on sometimes the light switches can go bad and cause this to happen such as hood or trunk.Hope this has helped you out some!!

It sounds like your alternator is not charging. You may want to have it tested and replace/rebuild it if necessary. Many times the problem is that the brushes are worn in the alternator and it stops charging correctly. The brushes are usually attached to the voltage regulator and are replaceable if you have the parts and skill. You can also replace the voltage regulator/brush assembly as a unit.
Many parts stores will test your alternator for free.

Hello! There is a device called the MAP sensor. It is located after the air filter, and before the intake. A 3" to 4" plastic tube with a wire connector coming out of it's side; Connected with a hose in and hose out that connects to the intake. This is the culprit 90% of the time. Auto part stores sell it for around $80-$90. Check both hose for cuts or holes which allow dirt to enter after the air filter. The MAP regulates fuel flow. Radio Shack has a product called "Deox It. The catalog # is 64-4338 and it is used to clean electrical devices. Cost is around $15. Try cleaning it first and see if your trouble clears.
