My car engine started making this rough gruff long noise, I ignored it for three days but yesterday I came to a stop and put my car into reverse and immediatly my engine shut off.

There was still power but pushing on
the gas the car wouldn't move
anywhere. I took the keys out and
restarted the car a few times, finally
the engine came back on and the car
moved foward. Drove on the highway
for a shopping center, the second I
pulled into my parking spot at the
center my car engine immediately
turned off and I ended up rolling into
my parking spot. Again I had to
restart the car a few times before the
power And engine would turn on,
finally got it to work and drove home
and again the second I started
coming to a stop my car engine shut
off. Also, along with the light
grumbling engine noise, there is a
high pitched sweeping noise. - I
opened the hood and it sounds like
the spinning belt thing is where some
of the noise is coming from. I'm a 17
and my dad is out of town so If there
is an easy way to fix this I'm
desperate!
