My buick 91 century would run perfect for about 20 minutes then die. Now it starts but stalls and dies when I depress the gas pedal. Could the cause be the torque converter cluth solenoid? Fuel pressure is at 40 lbs constant,new fuel filter replaced mass air flow sensor.checked idle air control sensor. Still the same.
TCC solenoid ,no . Crankshaft position sensor or ignition module maybe. . What engine does it have ? 2.5 or 3.3
Video's on youtube showing how to test
SOURCE: 1996 buick century 3.1 L,
unplug your mass mass air flow sensor an see what happens when running and let me know
SOURCE: 92 lesabre runs 4 minutes and dies
Make sure and check your ignitioin fuse if its out the car will start it just wont stay running verry long sometimes in most cases will turn over but not start
SOURCE: 1994 uick lesabre barely runs when pushing gas ped
also with request of pcv valve check does car shake or vibrate when trying to accelerate? if that is to be the case more than likely bad pcv valve.

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.
SOURCE: I have a 1987 Buick Century. That stalls out
I'm not Roger but can tell you this....if you have a bad crankshaft position sensor or a corrupt ECM....your car will do that.....last things could be the timing belt.
