It could be the contacts in the starter itself.there are 2 l shaped copper contacts in the starter that the bendix touches when it pops out. these wear down over time, i have 180 k original starter and replaced these twice , a couple of friends have done the same. the starter will work fine then just stop working . the toyota part number is : 28226-72010 , they are @ $9.00 . alot better than a new red top or a new starter, its an easy fix.
