Hi

I have a 1998 VW petrol Sharan which has just started to have a really
annoying problem.

I can start the car cold, drive for a few miles with absolutely no problems.
Either 2 things will then happen:

1.  I can park the Sharan, turn the engine off try and try to start 5-10
minutes later and it just won't start.  Turns over and fires and
occasionally chugs but just wont start.
or
2. Same symptoms as above but whilst driving.  Total loss of power and
eventually dies.

If the car is left 30 mins upwards it will then start and drive normally
again for a period of time before it happens again.

What I have done so far is changed to fuel filter and the crankshaft sensor
but to no avail.  I've googled around and some other problems it could be:
Ignition, Fuel pump, coil...........(no doubt probably more as well that I
haven't come across)

Just wondering if anybody else experienced the same problem and if they
found a cure, rather than me spending loads of money on each different
'could be this...'.

Any help greatly appreciated.
