VT2 intermittent stalling

[Saints10]

Hi Gurus,

First time poster hoping I can get some advice as Im going crazy at the moment.

For about the past 4 months my 2000 VT series2 executive (about 220k on the clock) has had an intermittent stalling problem. You would just be crusing along at 60 and then all of a sudden it would just cut straight out without warning (usually when im in heavy traffic with nowhere to go grrr). When it does this, the power-train and battery lights come on. At first, it would start again straight away after pulling over and then continue on and drive perfect as if nothing had happened. It would happen maybe every 3 or 4 days, and run perfect in between these stalls.

Lately, it has started happening more frequently (every day or 2) and sometimes takes awhile to get started again (sometimes up to 10 mins). Then, for about the last 2 weeks, it has began to refuse to start for sometimes up to 20 mins at a time (engine turns over, but fails to kick) - most times it starts straight away but occasionally it takes this time (usually at an inconvienient time like at a petrol station or in a train station car park). Ive noticed when it has these episodes of being hard to start, the power train light comes on and stays on untill I turn the car off next - then it starts again straight away with no light.

It has been to the mechanic several times, and he is pulling his hair out as much as I am because he can never catch the fault to find out whats wrong. I even gave him the car to drive around for 4 days, and of course it didnt miss a beat during this time. He has tried plugging in the diagnostic tool, but it does not show any errors at all.

Im at a loss what to do. Thinking seriously of selling the car if I cant figure out the problem. Any help you can give would be appreciated.

Cheers Guys

Crank Angle Sensor - When the sensor overheats, it stops transmitting a signal to the PCM. This signal usually determines where the crank is in its rotation, to trigger a 'firing' for the spark plugs. No signal - no reference point for the PCM to send fire signals to the DFI, so no engine run.

If you wait and it cools a bit, it can restart again. To confirm that its the problem, get a can of some very cold fluid. When it stalls, dump the cold fluid on the area behind the Torque converter. there are 2 sensors in that area. Cam angle sensor and Crank angle sensor. If the cooling lets the car run again, you have your confirmation.
