My A4 cut out abruptly when under power for about 30 minutes. When I put a jumper across the oil pressure safety switch terminals I found that electrical fuel pump did not make usual clicking sound. So i replaced fuel pump but no change. Then replaced coil and no change. Replaced leads from starter to oil pressure switch no change.
Finally, ran a jumper wire from +ve on battery directly to fuel pump and engine ran.
When I got back to the dock 1.5 hours later I disconnected the jumper wire and engine died immediately.
Advice please,
