Default Audi can't diagnose my engine problem

My '00 2.8 has been in the shop for 3 days now, and they still can't fix it. The engine cuts out, or misfires, or loses throttle. But this is an intermittent problem and it may not occur for hours or even days.

They first replaced the O2 sensor. They thought it worked, but before I got it home I noticed the same problem. The next day they replaced the accelerator pedal assembly (they thought the pots were bad). They kept the car an extra day to make sure it works and found the same problem.

My question is if/when they ever fix it, what will I be responsible to pay for? I already paid $650 for a new O2 sensor, but that didn't help at all. I know that they are spending a lot of time on it, but I can only pay for so much. They are paying for a rental until I get my car back. I don't want to find out that it was something simple all along, then have them charge me $2000 for 10 hours labor.

What is fair? And how do shops usually charge when they are troubleshooting a tough problem? And how do I know if this was really a tough problem or something they should have caught right from the beginning? Any thoughts?

Default Is the car throw any codes(DTC's)?

It would help if we knew the troubles that the car would throw when it does shut down. Is your car a 5sp or auto trans? How many miles?

Default Yes they do see some codes

When the problem occurs, sometimes they see stored codes on the diagnostics display, but not always. Often the EPC light comes on, one time the check engine light came on. I'm not sure exactly what the codes are, but they seem somewhat confused by what they are seeing.

Default Does this happen after the car sits, or

only after driving it a while. I had a Grand Cherokee that had similar symptoms, but only after sitting for some time. It would also be really hard to crank. I traveled alot and would have dealerships look at it everywhere I went. No one could figure it out. They would adjust the TPS, clean the intake manifold, replace plugs, etc. Once I got home, my local dealership kept it for a week. It was the fuel pump, kept to much pressure on the lines and the leak-by of the injectors flooded the engine. They felt so bad about taking so long they didn't charge me anything. Don't know if this helps. You should talk with the service manager about your concerns.
