2003 jimmy loses power on hills check engine light blinks stalls
DO YOU ALSO LOSE POWER ON HARD ACCELERATION? IF SO CHECK THE FUEL FILTER AND THE CAT FOR RESTICTIONS. IF THE CEL IS BLINKING OR STAYING ON CHECK CODES FIRST. THE STORED CODES WILL GIVE YOU A GOOD PLACE TO START.
Check for trouble codes.

Had similar problem with my 2001 pontiac grand prix. replace engine coolant temperature sensor. Vehicle may start , but run very poorly, blowing black smoke, running very rough and misfiring. Cost $15 autozone.

Change or clean the EGR valve and install a new catalytic converter.
This should take care of the problem.

The first thing I would recommend is that you change your fuel filter and recheck your fuel pressure once you do that. If is persists I would check your fuel pressure regulator as well. A fuel pressure regulator for a 1997 GMC K2500 ran about $45.00 and a fuel filter runs about $7-10.00. That's a lot cheaper to go that route first than to have to spend $350.00 for a new (Lifetime Warrenty) fuel pump that comes with a new sock and sending unit.
