1993 Volkswagen Eurovan

Computer problem
1993 Volkswagen Eurovan Two Wheel Drive Automatic 120000 miles

Hi, I have an Eurovan 1993 GL 5 cylinders. Since one year, a problem stops me from driving it. Here is the situation: At any moment, the fire stops, the RPM hand goes crazy and the automatic transmision doesn't respond well. After a few minutes, the van restarts but can stop again anytime. The air sensor, the oxygen sensor, the grounds and the electronic ignition were checked. After, the coil has been changed and the van worked for about two months but the same problem came back. What's wrong? What is the source of the problem? Is it an engine or transmission computer problem? Thank you for helping me. I'm lost! JÉJÉ
