Car shut off, then when tried to start smoke came from hood

2 days ago we put a new battery in because it just died on
us. Tonight he head out do some errands and 1/8 miles
from our house at a stop sign it just shuts off. The light
panel goes crazy, first the oil light comes on, then the
traction control like, then the panel says something about
tire maintenance soon. Every time I tried to start it smoke
came from under the hood, it was a coolant or oil smell it
was a hot metal/plastic fire smell. It would not start back
up but sounded like it wanted to. We just can't keep putting
money into this car, we have 3 special needs children with
multiple appointments every week, but we don't have
another car and certainly can't get one. Help me please.
