95 Oldsmobile

Hi, I own a 95 Olds Silhouette 3.8. It has about 150,000 miles on it. I'm haveing a problem with it just going dead on me. I can be just driving, or sometimes just go to turn the corner and the van will just die. I have to wait about ten minutes and it will then restart. If you mess with anything like try to restart it before waiting ten minutes it will not start. It is happening more often now. Does anyone know what this can be? Help please.:frown:
