i finally got my 78 yota running. it sat for some time but i was driving down the road and just lost power i could not get it over 10mph. it has a new fuel pump filters and spark plugs any info?

 

It kind of sounds like a fuel problem. If the truck sat for a long time the gas tank could have rust in it plugging things up. Check the fuel filter to see if its full of rust. It could also be other things like the fuel pump or the carburator, but i would start at the tank and go from there.
