2000 Tracker Stalling out

Can anyone help me out? We have a 2000 Tracker, after putting gas in the vehicle it tends to stall out, (sometimes stalls w/o putting gas in)after about 20-30 minutes it will start. Does anyone else have a problem like this? What could it be?

Hi, I had a similar problem, first thing I did was change the fuel filter, it helped but in my situation, it tourned out to be the electric fuel pump. hope this helps...
