Need urgent help lads with prob on RST with cossie management.

1. Car will cut out for what appears no reason, just dies on me...usually when slowing or stopping at a junction. Some times it has just died whilst driving along at low speed.

2. Car drives fine then go to accelerate and it missfires...running but no power, done this today, put clutch down and up...when done this car drove fine again...then started to cut out five mins later.

Any ideas?....pulley sensors?
