You could have received bad fuel or you have a hole in the venting lines. Also put on a locking gascap in case of vandalism. Its obvious this is not good for the system.

You should first check the venting lines at a Repair shop with a "smoke machine". This will show how well the fuel system is sealed. If they find a problem have them repair it because they can recheck it.

The gas tank should be cleaned or replaced. You can use an aftermarket tank of the same capacity. I do not know if the vehicle is operated around salted roads or on the Coast. But it is a 12 year old vehicle and gas costs too much to lose on a bad tank. There should be a high pressure stainless line that can fail too. It should be inspected with the tank.

Keep a clean filter in it. I've rebuilt carburetors on older models that had sand throughout. Hopefully the old filter protected the engine from the sand.

Had bodywork done and feel that sanding dust may have gotten into the fuel line. Could this have happened. Truck dies at stops

No, and even if it somehow did get dust into the fuel system, a simple change of the fuel filter should remedy the issue.

Do i have to buy another fuel pump for my car because my 4year old put sand in my gas tank

No, but you have to have the tank removed, drained and thoroughly cleaned. If left, the sand will end up wearing away parts from the fuel tank on the fuels travel to the exhaust manifold. The worst bit would be sand getting stuck in the oil on the piston rings and wearing the cylinder bore away.

I have a 2000 Chevy Sonoma ZR72 what would cause

Clogged fuel filter or trash, IE; Sand , in the fuel tank. Check filter first. Back wash old filter into a rag and see what comes out.. If you see or feel fine grit, then a gas station gave you a load of sand and you will have to drop the tank and clean it out, thoroughly. If you continue to shut of and restart to drive, then the sand will work its way through the filter sock in the tank and you will be buying a new fuel; pump. $300.00. Been there, done that.....

I have changed everything under the hood, maf sensor, coil packs, spark plgs, egr valve, h2o sensors, fuel filter and still have a miss. When I changed the fuel filter I found lots of sand in the filter,...

as long as the sand was caught in the filter, and u replaced the shouldn't. it could be something as small as a collapsed or dry-rotted vaccuum hose, or as big as a bad head gasket. I would run down all of my vaccuum lines and check them first, and if they all are ok, i would take it in and have a compression test done.
