mk3 golf 2.0 gti runnining problems

can any body help with a mk3 golf gti 2.0 8v  which suddenly cuts out when driving
did it a couple of times but now getting worse
been in to vw,s but couldnt find a fault
seems to start and do short run or just run for sbout 10/15 mins snd then cuts out ,  will eventually restart and then do the same

there not a mk3 golf forum?

i know its not a mk 3 forum thats why i posted under general
as i also have a mk 3 as well as restoring my mk1 cab
as basically all the same mechanically was trying to draw on the wealth of experience on this site
so if any one has any ideas  im listening

I had a Mk3 1.4 that used to cut out when I dipped the clutch, I was told it could have been the lamba sensor, but I part ex it for a mk4 TDI instead

Knowns fault with MK3s are ignition switches playing up and duff cheap fuel pump relays that VW fitted.

other very commen fault is the coil and distrubuter

Sorry to take this off on a tangent, but my engines getting tired, so when I take it out and rebuild it (later in the year) I'm thinking of getting a mk3 2.0l Gti engine and putting the mk1 manifold on it (so I can keep all the original mk1 injection set up in place)  the mk1 dizzie and flywheel/clutch .  Am I right in thinking it is a fairly straight forward swap over job to get this running in a mk1 ?

Its straightforward except its a tall block (16mm or so taller than a Mk1's 1.8 engine). Apart from that, its a nice swap but don't expect a big increase in power. I imagine the cam is softer too, so you might want to do a cam swap to a hotter one at the same time?

Back to the original question  it could well be the Hall sensor (fly hweel pick up sensor) losing signal, had a 16v one when i worked at vw that did the same thing every tec in the place looked at it and couldnt diagnose it untill an apprentice got hold of it and cured it

Cheers Paul, I'm not really going for a power gain, just going for a lower mileage engine and run it for 12 months or so, while I sought out the old engine (I dont rush these things  :mrgreen: ) and as far as I know the mk3 was the last to use the old style block??  :dontknow:

MK3 Renowned for distributor problems ! Replacement is the only cure .  

   

follow up result and solved hooray
       
after following and checking all suggestions and tried new dizzy/coi land module pack and varios other items still no spark (good job work in motor facors and only tried parts no expense there)got fuel pump working by bypassing relay so power still nothing
checked ecu relay under dash and hey presto ehen checked across terms found intermittant fault
changed relay and alls well cost 10.52 for new relay from euro car parts
