Started my car, turned on headlights, drove about a quarter of mile then my headlights, dashboard,radio, etc.. (anything electrcial) went off, and then my jeep started to run really rough. car wanted to die off. please help

SOURCE: engine dies, starts rough

Most large parts stores read codes free. Most common cause is crank sensor, but I'd have code checked before buying anything.

First, make sure you can turn the engine by hand. If you can't then the starter can't turn it either. Have someone else turn the key and look for the source of the click...may be a relay. Go over the starting circuit with a volt meter. Check for power at the starter main terminal and then with the key turned to "start" check for power at the trigger terminal on the starter. Check battery voltage and check relay operation.
You have a neutral safety switch on the transmission if its an automatic and a clutch switch if it's a stick. Check them as well. Make sure battery grounding on fender and block are also clean and secure.

p0340 is the cam shaft sensor, this will cause it to cut off while driving, hardtime starting, p0351 is the ignition coil A primary/secondary curcuit mal function. p1391 is ignition system misfire, this could be plugs, wires, or coils. first of all have the cam sensor changed and it may correct the rest of the codes. when fixed turn light off with obd2 scanner. if you do not have one, then any auto parts store will erase the codes fo free of charge.

The miss,does not just come and go,if it is a engine valve,replace the coil and boot,go from there,if this does not solve the problem,then the injector is gone out,or going out.If it is a engine valve,the miss would never get better,then worse,it would be the same all the time,get him to run a air compression test,get the valves up(close)and see if any air is detected threw the exhaust,or the intake,it will be present if the valve is the problem.
