88 tercel acts like it is running out of gas when warm
So the title says it. Runs good cold but when it warms up, it acts like it is running out of gas when I accelerate past about 2500 rpm, in the lower gears. If I don't warm it up and just drive it, some time down the highway it just loses all power, so I let it coast for a bit and I can get almost back up to speed and then it does it again. I was thinking that it was the fuel pump because that is what it seems like but it does'nt make any sense that it only happens when the engine is warm.
Does any one have any imput? Some body has to have run across this before.
