Scorpio still goes to but that was it then

Hello together, have just had a problem with my Scorpi 2.9 24V Cosworth 207 PS Built 1996. He jumped when I started it earlier but more not. Stuttered then totally and ran really restless. He does not react to giving gas at all, only as if he wants to go out but can not. What could that be? Hope someone can help me, depend on the car and can not afford me moments of great failure of my fat baby. I am grateful for every tip. Gruss masskrugbie r
