2000 Honda Odyssey

I have a 2000 Honda Odyssey which
I'm so lost of words trying to figure
out why did my Honda shut off
completely after hitting my back
right tire hard against it..after hitting
the curve it turns off as if I was out
of gas, so I tried turning the van on
and just when I heard it go on, it
ends up dying back down where I
stayed stuck. EVERYTHING was fine
dropping my friend off but after that i
kept starting it over n over but the
same issue kept on (Started up &
then Shuts off completely) I changed
fuel pump installing a new one. After
putting it in I starter up it stayed on,
only this time it stayed on for about
2mins..but then shuts off even if
pushing gas pedal making it sound
like it was flooding or bogging is
what they call it..but other then that I
don't know what or how to do this on
my own if I don't know cars or to
repair them but for now I need
answer on what could it be
