Vapor lock on 1994 Ford Explorer

Just like another question...we would go to the store and come back out and the explorer wouldn't start. We would have to wait for about an hour then it would start. Could it be a fuse or a relay switch for the fuel pump?

It's hard to know without a diagnosis. If the problem is verifiable then perform a no-start diagnosis while it is acting up. Check fuel pressure, ignition spark and injector operation when it doesn't start.
