MY 1992 BUICK LASABRE CUTS OFF AFTER DRIVING IT FOR ABOUT 30 MIN THEN IT WILL NOT START RIGHT BACK. IT THEN WILL START ONLY GO FOR FEW MILES THEN IT CUTS OFF AGAIN. IF I LEAVE IT ALONE FOR ABOUT 30 MIN IT WILL START AND REPEAT THE SAME PROCESS. DOES ANYONE KNOW WHAT COULD BE CAUSING THIS. I WAS TOLD BY A FRIEND IT COULD BE THE INGITION Relay but when I search that part there does not se em to be that part for my car any help would be great

I have a 1996 Lesabre. I had a similar problem that slowly got worse. I brought it to two different mechanics that did diagnostic checks and could only "suggest" what to replace to fix the problem. Their problem was that it wouldnt stall out while they had the mv. After replacing a bunch of sensors and the fuel pump/ filter, I solved the problem by replacing the Crank Sensor. Its located behind the lower crank pulley on the 3.8 lt motor. Hope this helps!

three core plug hahahah it has 3 coils crank sensor is located at the crank pulley it sits inside and creates a magnetic field and produces a low ac voltage 5 ac volts or less module then converts it to a squar wave to fire injectors and coils

Your fuel pump might be going bad. The reason why it cuts off is the fuel pump is pumping just enough to run it for a x amount of time that's why it shuts off but while it's off the pump is pumping fuel into the lines. If it's not the fuel pump then it might be your injectors.

SOURCE: car shuts off every time you let off the gas.

The first thing I would check is the idle air control motor located by the throttle valve. Sometimes they can become caked up with carbon and cleaning them out with carb cleaner or replacing them will fix the problem.
