tracker dies just like it run out of gas , might take half hr. to restart

try to change your fuel filter its by your gas tank

I've been having the same problem with my 1990 Geo. I changed the fuel filter and that wasn't it. Pryor to that I had a new timing belt & water pump put in. The timing was not set correctly so it is still the same. I've had several mechanics look at it and they all agree that the whole thing (timing belt) has to be pulled out and reset. So we will see. Good luck on your Geo and mine! I'll let you know if it works.
