I have a 1996 Isuzu Rodeo with a 3.2 L . The U/S light is staying on and the check engine light is also on. When I put it in 4WD it lost all electrical power and died when I came to a complete stop. Any suggestions?

take it to Autozone (if you have one) and have the codes read.

U/S light? Sounds like your battery or alternator is bad. Putting it in four wheel drive puts a big load on your power supply. If you have a multi meter you can check your battery voltage and starting voltage (just unplug ignition and turn over).If battery voltage drops below 9.6v and starter is fine could be a bad battery. Also when it is running check voltage. Charging voltage should be 14.6
