FD Shutting Down When Warm
So I've been having a problem with my 1995 FD for a little while now. It suddenly started sputtering and had a couple problems with stalling. I replaced the fuel pump, fuel filter, speed sensor, and spark plugs and those problems went away. Then a day later the car shut down and gave me an exhaust temp warning light. I let it cool down for 30mins and it started up again. The engine wasn't overheating at all.
Then to try and fix the exhaust issue I replaced the cat with a test pipe. The car drove a little better, but when it warmed up it died again. I just idled it cold to test, and as soon as it go to operating temp it shut off.
I'm thinking the injectors could be at fault. I replaced them awhile back to fix a fuel leak, but it was a used set so maybe they were bad.

Ok, so more info now. I looked into the FSM and for engine bucking/lurching and stalling at cruising the culprits could be:
Fuel pump (replaced with OEM last year, replaced with OEM-type from rockauto two weeks ago)
Fuel filter (replaced two weeks ago and last year)
Spark plugs (replaced two weeks ago and last year)
Ignition coils (not replaced, assuming original set with approx 80,000miles on them)
Injectors (replaced with a used set to fix a fuel leak, fixed the fuel leak but maybe the injectors were bad?)
MAP, Oxygen, Knock sensors, ECU, TPS adjustment
Fuel thermosensor (list exact condition, engine stalls at idle after warm up)
My most likely guesses are thermosensor or injectors.
[Edit:] Upon more research, it seems like a bad thermosensor would put it into limp mode.
