While driving all the lights in the car will come on for 2seconds and turn right back off. Every once in a while this happens. I dont know what the problem is.

Do you mean the instrument cluster lights? If so there is a possibility the battery cables or a ground cable is a bit loose, I call it a voltage excursion and it is distracting even if harmless. Check the battery and the charging system and repost if more help is needed.

You know. When you first turn on a car, all the lights will come on then 2 seconds later, the light will go off but in this case while I am driving all my lights will suddenly comes on and like 2 seconds later then goes off. It happens once in a while when I am driving. I am thinking maybe the wires are touching each other somewhere.

This could be a comfort relay chattering on its contact or a intermittant connector, intermittant issues can be very difficult to pinpoint and I usually start with the basics and try to eliminate what it isn't, good luck with it.
