have the alternator checked. when alternator dies, alot of vehicles start dropping of un essential items to conserve power
Have your battery and charging system checked. If ok, I'd look at the ground wire on tranny hump on passenger side. 1 screw behind carpet, that ground handles a lot. Would also look at ignition switch.
