Has anyone has this problem? I have a 1992 RS 305 V8 and twice, once while driving and once sitting at a stop light, the car just stops running. The best way I can describe it is as though someone has turned the light switch off. I wait a few minutes and I can start it again and it seems to run just fine. Have had it to the shop on both occasions and they cannot get the problem to duplicate. Had the fuel pump relay switch replaced about a year ago. Anyone have any thoughts?
