Electrical ? Please help

Hello, I’m new here and I don’t know if this topic has been described before. I try to briefly describe the problem….so, if the engine is cold, it will take a while to start…after a short time the engine will go off again…as if it doesn’t have a sprite anymore..the new start will take a while….when I start, I have a kangaroo under the back…i.e. the speed drops to 0, but it will come back again…it will last until the engine is warm…then it will run like a one…..there was something new before yesterday….there is no light left at the front, the speed has stopped at 7 thousand, the battery lamp is red(when the brake is light red) temp display is not possible… I had changed protection, so it was short, until I drove and the car stuttered…there was everything out again…I’ve got n escort bj. 93…can anyone help me?
