What can cause my car to have all the gages stop working and the heat kick on? on 1994 Chrysler LHS

I can drive my car and it will run fine, but then there are times that i drive it and all my gages stop working and my airbag lite and heater kick on. Or I can drive my car and it jerks really bad and then kicks it self off. What could the problem be?
