My stock 91 (454, the one in my signature) is having problems staying running. Just at random it dies but will not stay running for more than 5 minutes. I can turn the key back for a minute or two to off, then it usually restarts.
I already replaced the intank fuel pump, strainer and fuel filter, it has a fairly new throttle sensor on the TBI and the injectors look like they're giving good pressure (when it runs).
A friend talked to his dad who is a master mechanic and he suggested the fuel pump relay but I am not sure where that is on this beast...

any other ideas?
