Question 97 540i hot start problem

Hi, I have a 97 540i that has a problem starting when the engine is hot. No problems starting when cold starts first go every time.
Symptoms :
-turn key when engine is warm motor tries to start will not fire.
-starter motor keeps running till car eventually coughs and splutters and finally starts (with black smoke)
-after finally starting ending idle is quite high as if it thinks the engine is cold and returns to normal after a few minutes.

Could this be a temperature sensor problem with the engine thinking it is cold?
