What's Wrong with my 1995 Jeep Wrangler?

Problem: About once every 10-15 minutes while driving, the engine occasionally sputters, chokes, and loses power, but then it recovers. It seems to do it most while accelerating, and at 2200-3500 RPMs. Check engine light is on. It sounds like it's misfiring, choking, sputtering, but it is definitely losing power when these incidents occur.

Coincidence: This started happening around the same time I started towing my light fishing boat behind it.

What I've Done (with little positive affect):
- Replaced the fuel filter
- Replaced the fuel pump
- Replaced the spark plugs and spark plug wires
- Ran engine cleaner fluid through

Stats:
1995 Jeep Wrangler Rio Grande 4x4
