I agree with John, it has to be an electrical problem. Some things to check:
1. The 99 fuse box is notorious. Try rolling the ceramic fuses in their holders, they get corroded. And/or replace them with the glass tube type. They are available with pointy ends that will fit. The rivets that hold all those metal fuse holder pieces together can also loosen and corrode with age. When the car is running with lights and cooling fan on, see if the fuse box gets hot. If so, replace it or solder the riveted connections for better current flow. I drilled out some of the rivets and replaced with small brass nuts and bolts and it fixed my problems.
2. Clean all ground connections especially in the engine compartment and in the trunk for the fuel pump. Corroded grounds is a common source of problems.
3. If neither of the above works, check the alternator and voltage regulator.
Good luck!
