Could be a head gasket that is losing pressure going up a hill with the added strain.

2004 chevy trailblazer.. runs ok on flat ground.. going up hill it loses power.. I've cleaner the injectors and replaced the fuel filter... Any ideas on how to fix it ???

Ok that's sounds like a fuel delivery problem or you need more fuel in your gas tank but if it's full get it scan and you should find out what the problem is but I think the fuel pump maybe going out , get a fuel pressure gauge and check to see what the pressure is like
And it would be a great help if you park on a hill or slop while checking the fuel pressure now if the pressure drops then you should replace that fuel pump and change the whole module because am not sure if it's a possibility the module it's self maybe bad

Losing power up one particular long hill

It sounds like a tranny problem. Without more info kinda hard to diagnose. The simplist thing to check is tranny fluid. If its low, going up a hill will pull fluid out of the torque converter. It could be the converter itself. It could possibly a fuel problem, but unlikely. Hope this helps. John...
