93 s10 blazer 4.3l cpi engine problems

Can any one help me!!!!!!!! I have a 93 s10 blazer 4X4 with 4.3l CPI. The problem Im having is when the truck warms up to normal temp it shuts off and will not start. Let it sit though bout half an hour and it will start back up. Talked to some mechanics, they gave me some way to go. Here's what they said I should check and have done. NEW distributor, rotor button, cap, coil, fuel filter, and computer (ECM). Not sure where to go from here, can any one help me!!!!!!!!!

Proper testing before throwing all of them parts at it.
Because it may be another problem.:sarcasm1:

Does it quit on road or sitting at a stop?

Is it a certian time or just a certain tempt?

Is the idle holding up good RPM's?

First check for lose of spark or fuel pressure when it quits.
Post back which one it is losing.

Any codes or check engine lights?
