Im suspecting either the fuel pump or fuel pump relay. I will just be cursing down the road and it just dies. The next day or some hours later however, the car will start right up making me think the relay is over heating because the fuel pump is old and straining it. But im not sure. There are two 5 pin relays that are identical that have something to do with either the fuel injection system or the fuel pump. not sure. Any help diagnosing the problem would be greatly appreciated.
Thanks, Taylor.

Very common for fuel pump relays to die like this. You will need to hunt for wiring diagrams on the web,from a place that respects copyrights, as we do here at MVS.

Once you identify the fuel pump relay, you can jump the signal terminals the next time it fails, to see if that is root cause.
