My 1997 Pontiac Grand Prix stalls out when I am driving it is radom never the same conditions but it will start if I just wait what could it be??

it could be a number of things - dirty or clogged injector(s) - dirty IAC - poor spark - clogged/dirt fuel filter (meaning just replace it)

Try replacing the fuel pump resistor. I think that they go out more often in the 97's more then any other year
