BMW 520i 1989 Auto

I bought the car about a month ago, 2 weeks ago I had the exhaust manifold gaskets replaced but since then it cuts out for no apparent reason, it will cut out whilst driving or idle-ing, it will sometimes re-start itself if the car is moving but today it wouldn't start, the car was turning over but wouldn't fire up. the only difference on the dash is the green row of lights underneath the speedomiter (from left to right, a few green lights, then amber then red), one of the green lights are on. It also seems to be loosing fuel from the timing box (sorry!!) but the jubilee clip looks fine. Its also loosing water but I have seen a section on this from other posts and will sort that out once I have figured out whats wrong with the engine. HELP ME PLEASE!!!!!!!

The green, amber and red lights are your service interval indicator count down. All green means its recently been serviced, just amber means its due for a service, amber and red means its over due.
Your cutting out problem sounds like loss of cylinder compression on the second stroke in some of the cylinders. Changing the exhaust manifold gaskets shouldn't have affected this, but you never know, especially if the head gasket is disturbed. Or some of the piston rings may be worn.
A dodgy head gasket may also account for the fuel leak, if your idea of a 'timing box' is the same as mine.
