Thanks Jagzpanzer. The only problem with that theory is that the engine should die immediately upon reaching 176 degrees F+/- and it doesn't. It runs just fine at its stable temp of 192 degrees until I turn it off. If I restart it immediately, no problem. If I wait ten minutes, it starts and immediately dies after 3 or 4 seconds with the throttle having no effect. If the pump were seized, it should have drawn enough current to have popped the fuse and it didn't. I have a fuel pressure gauge that I can attach to the Schrader valve and measure pressures, but haven't gotten that far yet. I checked for ECM and CCM fault codes via ALDL connector and there are NONE; either C12 or --- everywhere. Now, I have had a ham radio license since I was 15 and what do you folks think of this theory? Jerry and Mark, need some input here if you have a chance! When the engine is turned off after heating up to full temp, the plenum gets hotter. Could the TPS sensor or the manifold absolute pressure switch be causing symptoms like this??? I thought about the CCM/ECM (the one under the hood!) heating up so I purposely left the hood up with my last test to prevent it and was still able to reproduce the problem. I THOUGHT that I smelled a fried electrical smell coming from the vicinity of the TPS sensor when this first happened, but could have been mistaken. My understanding is that the TPS sensor is just a potentiometer that varies output from about +0.5v at idle to +5.0v at WOT. I checked the fuel regulator, the diaphragm is intact, but sucking on one of the hoses going into the plenum did have a bit more gas odor than I would have thought. The hose to the MAP is intact and the short one going from the regulator to the plenum is new (from Jerry). Checked them both. Starting to really suspect that MAP sensor becoming unstable/defective when heat soaked. Friend Goldcyclon, what is this about a fuel bypass harness that I just saw? Did I miss a group buy or something? Did you get the metric pins for the shock gears that I sent you? Thanks, guys. We'll get this fixed and it will add useful info to our database for when it happens to somebody else. Thanks for the help, as ALWAYS! When that car died, it did so in front of a local repair shop. I had enough sense to have it towed home. Guarantee you that they had never even heard of an LT5 before and mine wasn't going to be their guinea pig. You know, we folks on this forum have become the world experts with regard to that car and you folks on this forum make me feel like a knuckle dragging idiot!!
Thank again!
