Might want to check your gas tank. I have seen plenty of problems caused by a rusty tank.

if the SCV's are still hooked up make sure they are working correctly. i know u said u went over alot, does seem fuel related (filter, clogged sock). or chitty plugs, weak spark, mafs.

scv = swirl control valves = butterflies (on s13's). i think they open at 4K or something, if they were stuck or being sketchy.
