mk1 golf 1800 gti '82 starts and dies

having problems, will start and run but after 50 seconds cuts out and dies, will start up again only to do the same thing. if left for say 3 minutes it will drive/tick over for a little longer.
what could cause this?checked the coil and the tci-h on my mates car and they are fine. :dontknow:

Are you sure this fault isn't fuel related?

may well be, i have just put a new fuel tank, pump,accumulator, injectors, metering head and fuel lines in. so i do hope not.
however i removed the module and the coil, tried them on my mate car and they were fine, have put them back on my car and it runs fine now, just need take it for a run as it may still break down under load.

Sounds like a dodgey connection somewhere then, just go round and check all the spade connectors and stuff for corrosion and poor electrical connection.

fuel pump relay?, it primes when you turn the ignition on but does the pump continue running once the engine is started?

defo not the relay, fuel pump seems to prime after its cut out. mine has never primed on ignition.

some do some don't.

try cleaning/ drying  out the hall sender unit attatched on the side of the dizzy

ok just taken it for a drive around the block, was ok on the first 2 laps, on the third started to splutter and on the home straight died, started up again and drove the rest of the way home, but it progressively loses revs??
