car died twice help me out

[IThinkImFast]

hi,
i almost ran outta gas this weekend infact my car stalled out going up hill and i was in luck to be at a gas station and i was able to restart the car going down hill to drive into the gas station.....long story short i had to fill up with 87, usually fill up with 89 but they were out. Anyways while driving a few days later my car died while breaking, no ses it just died but i started back up, i did have a check guage light on though you kow the one when gas is out. Then it happened the same way again coming to a stop i stalled again, same things no SES just the check gueage light. Should i be worried? is it cause of the 87 gas?

It's wouldn't be the 87, unless it is dirty as ....well dirt. You might of damaged the fuel pump by running out of gas. That is the only thing I can really think of.
