Question about 1993 Buick Riviera
The car was warm and running normally. When I backed up slowly, it stalled. It started after 6 cranks. It stalled again at the next stop sign. Started again after 7 cranks, it ran rough, straightened up and a half a mile later, at 60 mph. it started running rough again. 20 seconds later, it cleared up. Made it home. The next time I drove it, I accelerated a lot, it made it 3/8 of a mile and killed. It didn't start again until the next day.
Not for sure but it could be your cam sensor. if the check engine light is on then take it to a parts store and they can run a scan and give you more information

Last time I had that happen in a car everything blew. I found out the root of the problem was my timing chain, but I can tell you, you don't want to wait to get that checked out in any case or you will end up with a lot more problems.

You need new timing belt and gears. Buicks gears are made of plastic, and become a big glob. Nothing for the timing belt to grab onto.

This sounds like a fuel pump check valve problem, if the fuel is not kept in the filter and lines by the check valve it drains back into the fuel tank and causes the kind of problems you are having, you can check this by hooking up a fuel pressure guage at the test port on the fuel manifold that supplies fuel to the injectors, run the engine and shut it down, note the fuel pressure at shut down (with the test guage hooked up), walk away for an hour, come back and check the pressure, it should not have dropped more than 5 PSI You can buy a universal fuel injection pressure tester for about $25.00, cheaper than having a shop run the test. If the pressure drops you found the problem, bad news is the check valve is in the pump, the pump is in the gas tank.

U have a problem in the ignition system, most likely the ignition module or the crank sensor are failing, it will strand you soon and not restart, have it checked ASAP.
