i have a 97 f150 lariat 4.9l that runs awsome drive it for 5 min it die's acts like it loses all electric to the engin,i replaced feul pump,filter,lines ect.know it aint a feul problem,but if i let it sit for an hour it runs great again for about 5-15 min,then just die's again for another hour or so
no sputtering,or anything like that,acts like its just losing spark

Sounds like an electrical short. Break out the DMM and start tracing wires.

Or while it's running pop the hood and start moving wires. If you move a wire or a loom and it dies you know you're problem is there. If it's a wire easy peasy. If it's a loom, open it up and repeat process till it dies again.
