Doesn't Pull like it should

[ctresky]

I was towing my 16 foot fishing boat today on the highway and my 97 V8 AWD was having trouble with it. I have towed the boat many times with out a problem but today it wouldn't go to much over 65. It has been a couple of weeks since last time i went to the lake but normally I can do about anything when towing at any speed. Any suggestions on what is causing it? thanks for the help.

Tune-up, fuel filter, air filter, O2 sensors, etc...
