Any suggestions of what it might bed now...
I would replace all of the spark plugs/wires. SEAFOAM the engine (Fuel), change the oil to a lighter weight oil, clean the throttle body, PCV-Valve, and replace the air filter. If you do all of these things and it still wants to shut off then I would replace the O2 and Exhaust Gas Sensors. Make sure that there are no fuel leaks anywhere and that you do not have any fuel in the oil. Getting a compression check is a good idea and having the Dealership put her on the Computer and checking for Missfiring would be my last idea. If none of those work report back
