97 Blazer starts hard and quits while driving

I own a 97 Chevy Blazer 4WD, when turning the key to the "ON" position the dashboard indicator lights do not turn on immediatly (average 10 second delay) or a few instances at all. Obviously I cannot start the vehicle when this problem occurs but when the lights due come on you can hear the fuel pump kick in and the dash lights up; the car starts right up.
Also it has died while driving, sometimes shuts down completely on others just a second or two then runs fine. Other then that the car runs perfect. Thank you in advance for your help.
