Defueling problem

[JohnB]

Pulling the trailer home last weekend up a series of hills, I suddenly lost power. Fuel presure and egt was fine. I stopped and disconnected my Powermax but nothing changed, could not get more than 15psi boost. This lasted 45 miles to home. Hooked up everything at home and it ran fine. Tonight, after redoing the PM connection at the pump I drove it. I was able to make it do it serveral times with the powermax off or set to 0. Will barely make 18 psi. Now working fine again, 25psi @ stock fuel setting. Acts like a stocker when you hit full boost and it defuels. Anyone have any similar symptoms?

I pulled our enclosed trailer to a race a few weeks ago. Every time I hit a hill it seemed like 1/2 way ip it my truck would lose a lot of power. I had my BD box on the lowest setting. Once I was a 1/4 mile over the crest of the hill my power would come back. It was really wierd, but I swear it happened. But, I can run unloaded at the max setting and won't lose any power. Any suggestions?
