Engine won't turn

So I have a common problem with my opel corsa
lite... Whereby the car would switch off randomly
and so I found out the problem which was fan,
after driving the car for a couple off months
without any problems, today car was driven at a
constant speed of 80 to 90 km/h and car cut out
randomly I've observed this by seeing all lights on
the cluster had come on and so I knew the car was
off, so the car was still rolling while I'm gear I had
then taken the car out of gear and tried starting it
car wouldn't swing so I tried kicking starting while
car was still in motion while doing that the car
would start slowing down as if I was pressing
brakes so I pulled over to check, engine bay was
cool, oil and water was checked again as I also do
before leaving the house and that was also
perfectly fine... So I tried kick starting again and
then front wheels would lock and I tried changing
starter, battery, coil pack and car would not start
please any advice on what could be the problem
and what can be done to fix it
