Haven't done this in a year.
Start the engine. While the engine is running shake the wiring between the key and coil +. If you have an electronic fuel pump shake the wiring between coil + and the fuel pump while the engine is running.
There may be a lose or intermittent disconnect in the wiring.
If you have an electronic fuel pump and there is wire that goes from the fuel pump to the starter let this wire loose at the starter and inspect it.
On my A4 the insulation was worn and the wire was shorting out back by the distributor where the wire turns towards the starter solenoid. Kept me guessing for many months.
