93 Explorer

The vehicle accelerates from a stop normally when cold. After it gets hot( ambient temp. 90 here now ), it bog down from a stop and either is not getting fuel or fire, I do not know which.
After traveling a short distance and while slowly pressing the accelerator as nomally done, it will then quickly gain RPM and start moving faster. Even when at top speed it seems as if it is struggling.
When the engine is turned off and allowed to cool it runs fine again until it gets hot.
In the last year the following items have been replaced:
Main computer, oxygen sensors, alternator, fuel pump and filter, fuel pressure regulator, PVC valve, plugs and wires, throttle position valve, throttle air bypass assy., idle air control valve, catalic converter, and fuses undr the hood. It has no EGR valve.
Does anyone out there have an idea or know a real tuneup guy or auto electric man in the Dallas- Fort Worth area ??
