Help 88 Impulse

88 Impulse, after about 10 minutes of driving, charge light,stop light,low fuel and brake light come on. Temp. indicator about quarter way on guage, car runs normal , Also blower speed goes out at same time, Help

sounds like a weak electrical system. The battery is on its way out or the alt or both.

New battery, alternator puting out +14 volts, let it set for 30 minutes and it will be ok,untill driven for about 10 min.
