89 probe will not start

i was driving and when i gave it the gas it would slow down .i thought
it was the fuel pump so i put in a new one well i droveit for like 3 hours
and when i turned it off it did it again .could this be a fuel realy,or an injector? any help would be great.
thanks . Russell

I would get a fuel additive that you can find at any oreillys or autozone that cleans out the fuel injectors run that through there a good 2 times then if that doesnt help any give us a yell

i had an 89 probe that would do the same thing....next time it does it try the white button on the relay in hatch....mine was shorting out cause my filler tube for the rear windshield washer fluid was filling up the cubby thing with fluid
