Or the quad 4...

its definately not the 4. its the V6 model, which would make it 3100 by my recent research.

Start with plugs and wires, and also check out your coils.

I would also think plugs and/or wires. Check the coils as stated above. Seen some with rust and corrosion on the terminals where the plug wire attaches. The fuel pump usually start messing up after extended driving like an hour or more and when the vehicle is below 1/4 of a tank of full.

When checking coils..give them a good visual inspection for cracks etc.

I've had a fuel pump problem where it would get weaker the warmer it got.

Vaporlock can be the culpret to both problems.

LOL, looking through this post: In other words, there might be a lot of issues that are causing this.

Even if it lasts more than a year, getting worse as time goes on? For me, a new fuel pump made it go away.

Yup, but I can just start with the easiest, plugs and wires.
