My Riviera stalled while I was driving
about 60 the other day. Now it will
start and the engine will rev up, then, instead of idling, the car just
stalls out. If I let it sit for a couple of hours or so, it will run
for 5 or 10 minutes before it stalls, but it runs really rough. What could this possibly be?

My car runs good when it's cold but stalls once it warms up? ... In this situation, you can usually re-start the engine once it has hada chance to cool back ... it'll fill-up and exits fuel right up and out the vent tube which dumps it down the middle of ...
Possibly an ignition module or crank sensor problem. These are the two most common stalling electronics that will cause a stall when they get warm/hot and will then continue to operate once cooled down
I would look to see if you got a broken ground wire!!! witch are a big thing on todays computered cars. I know you have dumped a lot of money in your lawn ornament but one unhooked or dirty ground wire not making a connection can reak havick with everything, I would chk.for ground issues like around the fuel tank and where they hook to engine to body to frame or k-member.
Chances are your distributor cap, it may have carbon buildup ad is acting like a jumper wire to other spark plugs or it may have a very fine crack in it with carbon buildup shorting two plugs together. It's best to have it replaced, they don't cost that much and it's easy.
i know this may sound stupid but if your battery is old or a little weak on this vehicle the idle air control solenoid will act speradicley hunting for were it should be and the vehicle will stall.replace battery
These are also notorious for the crankshaft position sensor (CPS) failing intermittently and causing this same issue.Some of the vibration dampers (crankshaft pulley) were also known for the reluctor rings that trigger the CPS for coming loose and causing a timing issue and/or destroying CPS.Be sure to clean the mounting surfaces for module of any dirt or corrosion and apply some good dielectric grease to surfaces. Check the engine grounds and battery + connections for clean and tight as well.These are some other notorious problems with these. Good luck and hope this helps! Rate me please.
