Tracker will not start

I have a 95 Geo Tracker --wonderful little vehicle --I have never had a
problem of any kind with it. But....yesterday it wouldn't start. It
cranks strong as usual but, it just won't start. I thought maybe that the
fuel filter might be stopped up so I shook the vehicle a little and it
started but, only ran a minute or two. I'm thinking fuel filter or fuel
pump --I've checked all fuses. Any suggestions? Any checks I can make
before replacing things. I don't really like to do this process of
elimination thing.

do you have enough gas in the tank your gas hand could be bad since it
started when you shook the vehicle and it wont hurt to change the filter
when was the last time it was change you can also have something in the
tank blocking the fuel line
