Question Engine stops after 5 minutes

93 5.0 5 speed

I start the car cold and drive about a mile. Right about 5 minutes in, the car goes dead, back up, dead, up, kicking and bucking until it finally it is just engine dead. Everything else is still on (lights, radio, etc....) If I hop out of the car I can hear the fuel pump relay, IAC motor and EGR value clicking on and off 40 times a second. Turn the car off for 5 minutes, hit the road and the above happens again after a little bit.

Really weird stuff. I do not know yet if I have spark or fuel when it is dying. Computer ground? Bad ECU?

Thanks all for your thoughts.
