Help required.

My 2.0L 94 series III golf started stopping when hot about a month ago. Since then it has got steadily worse. Usually it will stop when driven from cold 10 -15 minutes into the trip when driving in dense traffic. It will usually restart with no problems but occasionally you might need to wait a minute before it will restart. It will not usually fault on long trips in lite traffic.

Work done to date:

First I got a Service & tune up just to make sure that it wasn't just stalling but the fault continued. I then got it checked for faults ( none found ) and got the mechanic to drive it with his sensor attached - no fault shown when car stopped.
I then started looking at the relays, there were two that would cause the car to stop when pulled out. The fuel pump relay (#167 printed on relay ) and a large double lenght relay ( #150 printed on end ) which has a pretty complex circuit inside. I started however with the main relay ( #30 ) which is meant to supply power to the computer - no change. Then the seperate fuel pump relay # 167 - no change. I have not yet replaced #150 and while talking about relays, I also noted that relay #18 gets very hot? but do not know what this relay does?
At this point the fault got worse where the car would not restart until it cooled down. The mech traced this to the coil which we replaced. The car will now start again when hot, but the original fault remains. The mech thought it might be due to a faulty engine speed sensor which is meant to be situated on the block just below the distributor, but my vehicle does not appear to have one?
From here we intend to look at the distributor. I have noticed a few similar faults listed in the forum and was hoping someone might be able to help.

I have seen the harness connector to the distributor cause this symptom.

*******fuel pump******* yes beliv or not
that F***** fuel pump give me the problem of my life i will stay on trffic for long time and my car will stall turn off, will start right back on this problem stay for a while until a GOOD MEXICAN mechanic from VW dealer toll me i bought the fuel pump in the company i work for cost me 180.00 (this pump is inside the tank you need to access from the trunck right hand side, )

note:if you are going to buy that pump tell your mechanic to check the fuel pressure,,,also to get to fuel pump you have to remove a big plastic nut you going to have to beat the s*** out of that thing so might bracket so before doing that i recomend to but the nut and the seal along with the fuel pump part number are:
1: 1hm 919 051m fuel pump
2: 1h0 919 133 seal for pump
3: 321 201 375 A union nut this is the one believe me you will bracke...... mine was so hard that i had to cut it...
