Car Hesitates while stepping on gas and turns off randomly

So I took my Saturn in for a routine Fluid change. Local Shop was running a special where they replace all your car fluids. While there I told them my car would randomly shut off some times. It would start right back up but this problem is very dangerous and annoying. So I left it there and they "fixed" the problem. They changed all my fluids and replaced all my spark plugs and wires, PCV valve. After picking up my car I noticed it started to hesitate while giving it gas. I did not have this problem before I dropped it off. I called the shop and they told me it was the cleaning fluid they put in the car and the problem will go away in a day or so. The next night the car shut off again. So I called the shop and brought it back. They had it for 3 days. They replaced the fuel filter, checked all their previous work ran all the tests on the car and the car still shuts off and hesitstes while first giving it gas. Does anyone have any ideas as to what might be the problem because no one at the shop seems to know hwat it could be

Just to add to this one I would make sure the spark plug wires were routed correctly when they replaced them. Because you said you didn't have the hessiation before the work was done. Also make sure the wires are all snapped in place tight. For the random dieing I would make sure the battery cables are clean and tight. Also any codes?Those years are known for bad crank shaft position sensors. They can do some crazy things as they die slowly also a bad coolant temp sensor can cause random dieing.

I had the same problem thinking it was Cat Converter, ended up being the Ignition Coil and needed new spark plugs and wires just had replaced 3weeks prior. Also had issues with Rocker Arm and the cylinders try looking into those areas. Good Luck.

Figured it out. It seems they hooked up the wires incorrectly after they changed all the spark plugs and wires. I found this out after doing a little research on my own. Thank you everyone for your help
