so i was driving home tonight on the freeway (60-70mph), and then out of nowhere, it just shuts off. the radio and lights still work, but all my gauges drop, cannot accelerate, and seems that my power steering seizes up because trying to get onto the shoulder was tough. if i try and turn it on, it will just crank and not start. again, all my lights and radio works, but no gauges. i just recently put in new spark plugs, distributor cap and rotor, spark plug wires, and brand new battery (optima). also, no check engine light came on. any help is appreciated!
