96 corolla electrical issues

[Rowdy]

I just bought a 96 corolla for my teenage daughter (it a fixer upper but runs great). We started driving this car and after a couple of days it up and quit while driving so I go to check it out and theres no power to several things including the fuel pump. Decided to go get a chain and tow it but when i returned it started up so i drove it home and it ran another day then crapped out for good. I replaced the circuit opening relay behind the stereo with no change. I have power from the switch but no power to the circuit opening relay which means no power to several things most important the fuel pump. I have racked my brain on this one and am at a loss. Any help would be appreciated
