92,000 miles is not "high mileage", and if a vehicle has chronic problems with power loss when under load, it won't matter how much gas you give it.
Also, when searching for a smaller cargo van from the mid 2000's, the Astro is unfortunately the only option in the U.S. Auto manufacturers realized that and are finally filling this need with the Ford Transit Van and the Nissan NV200, but as usual, they are behind curve by a few years.

Check your EGR valve, I also am having the same problem, and when you put your foot down, the problem gets worse!
