Sounds like a fuel delivery problem, replace the fuel filter and try it again, if it returns test the fuel pressure and flow, it could be a fuel pump failing or pressure regulator going bad. Does the check engine light come on when this happens?

As the mileage is low you could also have a build up of crud in the throttle body and on the air flow sensor, it would be a good idea to clean those as well. When was the injectors last cleaned professionally? They get cruddy too.

Not sure when they were last clean but I am going to check all these areas

When was the last time the plug wires were replaced. Sometimes when the are going bad it would cause it to feel like it is about to trip all over itself
