Driving down the road, the car dies along with power steering. Car will turn over but will not start

could be out of flue

You have a fusable link under the hood this is what i find for Saturn

I would get your brake pads and disc's checked they my be warped or damaged.As for the turning off problem i would go get and electrical test might be the ignition coil.

Remove the power steering belt from the power steering pump. Try to restart. Sounds like the power steering pump froze up. If the belt drives more than the power steering pump (like the alternator), you will have drained the battery and the engine will not start. replace pump, charge battery, replace belt....hopefully drive. Good luck.

alternator is going be the problem, when that stoped working the car was running off the battery when that died your car cut off.

yes you will need to replace the belt before you drive anywhere.

your i35 is a maxima

It could be either a bad fuel system or a bad spark system....
Fuel pump, fuel filter, fuel injectors, fuel regulator, spark plugs, ignition coil, distributor cap, etc....

take the car into to a repair shop to diag code for sartersI know I hate walking

If you replace your power steering pump has noting to do if your car die
if you have a problem whit your power steering system the only symptom you will have is a real hard steering wheel.

if your car randomly die may be a false contact on your crankshaft position sensor.

is located next to the crankshaft pulley (harmonic balancer)
tray unplugging it and cleaning the terminals whit electrical contact cleaner (sale on auto part stores) and if is to rusty you may have to change the sensor or the wire plug.

NOTE is CRANKSHAFT sensor not Camshaft they sound a like.

it may be a good idea to get you car scanned for trouble codes
most auto part stores do it at no charge.
