When starting for the first time, fuel pump comes on to prime the lines and establish fuel pressure...then it waits for you to crank the engine and electronically see the ignition pulses from the ignition control module. If it does not fuel pump relay is deactivated and no more gas is provided.
My guess is you are in the middle of a failing ignition control module. Works fine for a few seconds when cooled down but heats up quickly and fails when it handles the switching of the negative side of the ignition coil to ground. The electrical current draw through the module heats it up. Replacement is about $39. I carry a spare with me when it happened as you discribed to me on the road...start/fail...start/fail until the module completely died....you will need some heat sink paste from Radio Shack for mounting the new one...some modules come with it...two screws to hold it, electrical plug on the bottom and you are done...see photo...
