Is the 1995 Buick LeSabre hard to start?

I am working on 1995 Buick LeSabre. It will run ok for awhile, but then it stalls and is hard to start. Recent work on it was a normal tune up, Spark plugs, wires, gas filter, and air filter. I even dropped the gas tank and cleaned it out. Also, when I rev the engine, I can not get it to go over 4000 rpms.
