I have this problem with my Blazer where it will cut out and die at any moment, for any reason. If I try to immediately restart it nothing will happen. If I wait a few moments and try to restart it (and pop the clutch) the truck will fire like nothing happened. This happened last year and I replaced the computer and seemed to fix the problem for a while, then the same problems started to reappear. Has anyone else had these ghost type problems? At this point I am about ready to swap in an LS engine with NV4500 (including ALL of the factory wiring that relates to a swap like this) to eliminate this problem.

Any ideas?
