I have a 1991 4Runner that won't stay running. After I start it and and it idles down to 800 rpm it stalls out after about 30 seconds, and right before it stalls it acts like the battery is dead (gauges die, lights dim out), but when I check the battery after it stalls it reads between 11 and 12 volts. After it dies it will start up right away and do the same thing.
What could be the problem?
PLease help and thanx for any insight!!!
