[88 ranger gt]

i realize that this is a mstang site and my question is about a ranger, but i just put a 92 5.0L H.O. in and i have a problem. it runs great until it warms up, then pops and bogs down. if i trip the fuel pump shut-off, hit the key, reset the shut-off, and hit the key, it starts. it does not run very well and before i realized i could do this to get it started, it would not. is it getting too much fuel? what would cause this? help help help
