Car doing two things. When it won't start, nothing will come on that requires the key in the on position (stereo, windshield wipers, etc) but everything that doesn't require key works (headlights, brake/hazards, horn, etc). When does start it will randomly shut off while driving. Usually get lucky and will restart first or second time then does the thing I described first. Thought it was the Locktronics security system because that wasn't lighting up or flashing and it isthe ignition interrution type. Removed it and reconnected original ignition circuit. Did it again. Died driving and now wont restart. Anyone have any ideas? As information, key does turn, doesn't hang, springs back from starting position to on position normally etc. And when it shuts off while driving there is no warning and it doesn't sputter or backfire or anything. It literally just dies like flipping off a light switch.
