After the engine shuts off, does the car start back up easily? Do you have to wait any length of time before restarting?

Car fires right back up. I come to a stop, turn the key and am ready to go.

I had a similar problem with my LS3. It has been a while but it would just die coming to a stop. I assume you are using DBW? If so that is where I was told issue was Throttle Position Sensor in Throttle body. So I bought TB as that part is molded in on the silver blade TB. The new TB had a gold blade which created other issues. In the end I put old TB unit back on and got a tune after cam swap and problem is gone. Sorry this is not clear answer but it might be the pedal or TB causing you issue.

yes, what is your fuel pressure when this happens?

Can't tell as I don't have a guage specifically for this.

What these guys are getting at is that you are asking for input on a problem that you are having. Several people have offered up that you should check what your fuel pressure is when the car dies.

You then ask for other tips but you have not said what the results on the fuel pressure were.

This should be a step by step process. Easy Stuff first. Fuel..

It sounds to me like you have a fuel issue, with the funny filling (You should fix that first) then the car dying. It could be a failing pump or something on those lines.

Check the fuel pressure first. If the Fuel pressure drops, you have other things to check. Is it mechanical or electrical. Then dig in from there.

If the fuel pressure does not drop on the corners or the stops, you have another issue, could be a bad tune or even a loose wire or terminal somewhere.

Fuel pressure gauge is easy to hook up especially if you have a regulator.....also, why not a vacuum referenced regulator? Not many tuners like those and they dont run as well without a manifold reference.

Didn't know asking for multiple opinions/suggestions was such a problem? I APPRECIATE each one, and thanks for yours as well. The more suggestions I have, helps this small timer, cut down on wasting money. I've had the tank sent back to Ricks, and they had to adjust/modify the baffle. I am trying to run through suggestions - next will be a pressure gauge. I took the car out this weekend for a run and didn't have this issue.
