2002 Ford Explorer problem

[dozerman 1766]

I have a 2002 ford explorer that is making me go crazy it runs good at a idle but when you try to drive it it falls on its face check fuel pressure when you turn key on pressure go's to 60 psi when you start it it go's to 65psiso I can't figure out why I am losing power any help would be greatly appreciate

fuel pressure is normal. Can you rev engine in park or neutral? Any CEL light? Which engine? How many miles? Maintenance history? Possible catalytic converter issue?

Can Rev in park two 3000 rpms then falls on to it's face has over 200,000 just put new plugs and wires on it and o2 sensors but scanner is showing lean and random misfire
