hesitation on acceleration

[Flamesfan]

Howdy all,
1998 5.4 Eddie Bauer, 225k
Lately been suffering some rather severe hesitation/sluggishness on acceleration (bottom of the power band), then smooths out. Happens on acceleration from standing start, from acceleration at road speed, as well as at highway speed.
This only happens upon restart after truck has been sitting for an hour or less. Runs perfectly on initial start/drive or after it's been sitting for a few hours.
Truck never stalls out, but acceleration is quite challenged.
It was suggested that perhaps "bad gas" but several tank fills and bottles of conditioner and gas line anti freeze has not resolved.
Fuel filter was changed 7 months ago. Plugs and COPs are a year old.
No idiot lights on dash.
Any suggestions are greatly appreciated.

Scan your truck for codes regardless of any "idiot lights"

Sounds like the problem occurs only after heat has built up onto the component, or the engine.

Check throttle position sensor and MAF sensor regardless of codes.

Excellent suggestions, very much appreciated.

Have you literally ever towed anything downhill?

A good driver will have no problem towing 6,000-8,000 pounds with a half ton truck. I understand a lack of skills and experience can cause the complications you describe, just like those impossible plugs that many users have done.

It's not weather it can or cannot, but how well it does so...
Really have to explain this?
