I've got what I think is a sensor problem with my car.

The car starts first time whether the engine is hot or cold.
When the engine is cold the engine runs and holds revs fine, when it gets warmer the engine just cuts out.
When I restart the car it runs fine for 10 seconds then cuts out each time (even if I am holding it at high revs the revs just fall away and engine stalls).

The week before this happened I had the car on track and the radiator bleed valve came off and managed to coat the engine in coolant There was not too much water lost and the engine never overheated. Immediately after this the engine was working but now I have left it a few days the above issue has reared its head.

Any ideas ?? HELP.
