1994 S-10 4.3 shuts down after getting warmed up?

yes to your question on both about the crank sensor. same with the cam shaft sensor. i see that this is a new posting did you get the fuel pressure checked, if i remember right that model of s10 the pressure has to be checked with an in line pressure gauge. just curious, do you have a friend that has the exact same model of s10? if so see if his truck has the same sensor and equipment array as yours, if so pull his computer and stick it in your truck and run it until it warms up if it cuts out then you can rule that out. many folks will tell you that you have to worry about the prom id # ,,, not so. i know this from experience. just so long as it has the same # of o2 's, and all other sensors as your motor it will cross over. the spider unit under the intake plenum, have you gotten that checked out? it too is electrically operated. how about vacuum leaks? some only show up after the car is warmed up. just a few suggestions to try,hope one of them works for ya.
