Mk3 gti cabriolet 8v aag engine cutting out problem

[Bully195]

Hi
New to the forum as I've just got a 96 cabriolet gti 8v with engine code aag
It has a problem with cutting out when it has reached normal running temp 90, so it can be within 5 min if it's warm or last night it was 40 min and a few runs up the road then leaving it to tick over before it did it.
What it does is a can rev it then revs drop and it cuts out, I can start it straight away with full revs but then it just goes to high revs, drops and cuts again instantly and won't stop until it's left to cool down again.
Help would be much appreciated, I think the previous owner has fitted new dizzy n leads already, the engine has only done 80k and seems to run nice apart from this and idle fluctuations but I assume throttle body clean will sort idle prob!!
Cheers all

Sounds like the crank sensor to me.

As said, search.
Anyway clean the throttle with carb cleaner. If problem still there then replace the ecu relay if problem still there replace the fuel pump relay. If problem still there then go for the crank sensor

Thanks guys, I have researched it But a lot of the problems with cutting out are within first few seconds or minutes or whilst driving but they are starting again straight away! This is happening when the engine has got up to temp and then it's seems to happen when goes slightly passed this point and fan kicks in......then it cuts and won't restart just cuts instantly until cooled down again!
I will try the elimination process over the weekend both the relays have already been swapped as they where very warm!!
Is there a test I could do for the crank sensor?

Cheers again

Google U281 code reader, buy one, plug it in, scan engine, look up code(s), go to ecp and buy bits, take most of them back as they dont fit, lose temper with counter staff, buy from somewhere proper, fit, drive car again.

Right bought this and performed scan which threw up code 00515 camshaft position sensor (Hall effect sensor)- short to b+(g40): check CMP, if ok replace distributor!
I deleted this and it was ok when started up time after time with no more codes, so I ran it up for 40 min again until fans came on again then it cut out again and the same fault code has now reappeared?
What needs replacing and is the timing possible out? My friend looked at it with timing light but am I correct in believing timing has to be done with vagcam?
Cheers

if it comes up with hall effect sensor then that's in the dizzy... i.e. dizzy replacement.
