Try disconnecting the MAF and see if that makes any difference.

Disconnect and drive you mean?

What mods/tune have you got and have you had any changed recently or service done at VW?

Clue for me would be the loss of electrical signal for the fuel pump. If the ecu spotted this then it would certainly cut power as it would think that you have no fuel supply even if you have fuel pressure.

Ive got a Fuel Pump Control Module coming out today!
