Truck bucks sometimes when accelerating, shifts fine, no code light. Is it fuel?

What is your question?

2008 Tacoma 4.0 V6. When taking on a load or accelerating on an incline, the truck will buck like it's not getting enough fuel. I don't get a code light, Transmission shifts fine. Has to be fuel right? Bad injectors? Fuel Pump? Clogged filter? The filter never really requires any maintenance, it's inside the tank on these trucks. Never had a problem with these trucks, notorious for being long lasting. 120,000 miles.

What makes this problem better or worse?

Driving at 50 mph or less, steadily, is better
