Acceleration problem

I have ram with 318 4wd 110,000 miles. it runs great, but if you step on gas more than halfway, it wants to conk out. I ran fuel injector cleaner a few times, no change

What year Dodge? Is it the 1989 indicated in your personal data? Manual of automatic transmission? When was the last time you replaced the air cleaner? How many miles on it in the last 12 months? Has the converter ever been replaced or questioned?

Like Mr. Meehan says: Give us as much maintenance knowledge as you can. Fuel filter changed?

Dirt in fuel tank, fule pickup sock dirty?

Questions, questions, and more questions.
