Car stops randomly
When you say shopping you mean Stalling right. If yes then the usual cause is a failing Relay 109 which is the main power relay . The early golf had a grey relay which failed due to dry solder joints etc the modified black relay was issued to elevate the issue.
Relay 109 supplies power to these ,
Glow plug relay
- Fuse 32
ECM
Fuel quantity adjuster
- Fuse 34
Cold start injector
Waste gate bypass regulator valve (N75)
Change over valve (N239)
EGR vacuum regulator valve (N18)
Mass air flow sensor (G70)
- Fuse 43
Clutch vacuum vent valve (if equipped)
Brake vacuum vent valve
Relays for preheating coolant (if equipped)
Crankcase ventilation heating element
The ECM supplies power (and sometime ground as well) for:
Fuel cutoff valve
Cruise control switch
Manifold (intake) air pressure/Intake air temperature sensor
Needle lift sensor
Engine speed sensor
Engine coolant sensor
Closed throttle position switch (part of "go" pedal)
Kickdown switch (part of "go" pedal)
Throttle position switch (part of "go" pedal)
Fuel temperature sensor
Modulating piston displacement sensor
The ECM also communicates to the instrument cluster electronics and transmission control module (on automatics).
As a result of this, you can see why if the relay starts to cause power to flicker, or voltage drops, for all of these components, the results can be "unpredicatable" and none of them desireable.

The parts aren't really that expensive, it's the labor these places charge an hour. Call around and see who can do it the cheapest, unless you want to do it your self.

Either immobiliser is not reading the key or need to reprogram keyfob.

According to what you have mentioned it seems that the weight is far heavier than normal. But as a test I would suggest you test vehicle without towing anything behind. See if there is any difference in temp. Hope this helps.

First I would check to make sure you have the proper fuel pressure at the pump - you should have 2 pumps - one that delivers from the tank, and a high pressure pump for the injectors. Make sure that both are delivering properly - you may need to prime the pumps for quite some time if air got into the lines. Also make sure the cam / crank sensors wiring has no corrosion and is making proper contact. Between 0 to 300/400rpm the signal can be slightly erratic until the engine is started so I would not worry too much about that.
