Iv replaced coilpack distributer cap rotor button plugs and plug wires.... when my 97 360 warms up it falls on its face.... doesnt spit or sputter just loses all power completly when u give throttle... idles fine and doesnt completly die just wont rev or throttle at all untill it cools....any advice? Maybe tps?

sounds like a fuel problem, I think your suppose to be around 30lbs at the rail....start there and report back

96 and up is 49 psi at the rail, this truck still have a catalytic convertor in it? If so it might be plugged.

I didn't see a pre-cat O2 sensor on that list.

Missed that you are new here, Welcome to RF.

I second that: fuel pressure check, and catalytic converter check. Does it ping? Any CEL codes?

Fuel pressure, cat check and o2 sensors.
