Have you checked the fuel pump relay? The one beside the KLIMA if you have 1.

Last week, I had an episode of the following:

1) Car decelerates when driving like brakes were stepped out but I had my foot on the acc.

2) Car shuts off totally when driving slowly.

3) Car starts but shuts off by itself after 2 seconds.

I replace the fuse for ignition in the fuse box and moved the Fuel pump relay around. That seemed to solve the problem for now.

See if it helps, yours is a different car.
