We have a 91 astro van. When driving noticed speedometer and all other needle gauges were not working. Van was running and starting no problem at that point. Soon after stopped somewhere got in and Van was dead not even a click BUT horn worked. After a few minutes started right up drove home and when I tried to restart it was dead. Checked next day dead. Then jump started it sounded great ran for maybe 5 min then idled rough and pittered out. Window wipers were very slow as well. It will jump and start sound great and then after about 5 minutes or so will start to idle rough and putter and die, applying gas does not help it actually seems to cause it to die faster. Gauges never start to work. it seems like I may have a few problems that seemed to happen around the same time? Any ideas??
