I agree with caine, crankshaft sensor.
See this link for more info on a previous case.

cant actually remember on these things ,so have a quick look on the top of the gearbox bell housing where it meets the engine block.you'r looking for an electrical doodad held on by 2,10 mm hex heads.this (if it has one) will be the crank angle sensor.notorious for your symptoms and first look at for renalts that dont like starting.if no cas ,sorry for wasting time.
