When I first had the problem, I would be going up hill after driving for 20 miles or more. It would slow down, lose power, sputter. I took it to my mechanic and he changed the fuel filter. It didn't help. The next time it happened I drove about 20 miles, then on flat road went from 55 to 20. I stopped at a station and put in $10 of gas and coolant. IT ran fine the rest of my trip.. I had my mechanic check the radiator and he saw nothing wrong. What could be causing my problem?

sounds to me it could be a plugged catalytic converter. the symptoms are runs good , no strain, or on the flats, then loses power with exertion, or long uphill to the point you think it's going to just quit on you. easy test is to unbolt the catalytic inlet, and give it a quick test run. sometimes you can tell by having someone race the engine while you monitor the exhaust to see if enough comes out of it. usually happens over 75,000 miles
I have a 98 punto sporting nd today it started running like it was misfiring but wen i accelerate slow its fine but wen u accelerate as normal it spits and splutters :'( any suggestions??i have change fuel filter nd injectors ????
it sounds like the fuel pump, the reason I say this...When you first start it up it runs great, after a while it has no power, if you climb a hill it will slow down and sounds like it is backfiring. Hope this helps
This sounds a lot like a bad TDC (Top Dead Center) sensor. Of the many sensors on this model vehicle, the TDC sensor failure is common and is one of the few sensor failures that will disable your vehicle.
THOSE VEHICLES HAVE A SECONDARY FUEL PUMP THAT FEEDS FUEL TO MAIN PUMP UNDER VEHICLE. THE SECONDARY PUMP IS INSIDE THE FUEL TANK. IT IS POSSIBLE THAT THE 2NDARY PUMP IS STARTING TO SEIZE ON YOU. CAUSING POOR FUEL PRESURE AND MAKING VEHICLE TO LOOSE POWER
