Car lurks forward and has stalled/lost power

Yesterday the vehicle started to lurk forward like it was gasping for air or had a quick surge of gas. It already had a rough idle, so my first thought was air intake. That night, I cleaned the throttle body. It was running well, with a random surge at about 2500rpm in 2nd gear during acceleration. When I filled up my gas tank, I put in injector cleaner. I didn't realize until it was in that it was also upper cylinder lubricant. The car didn't like that at all. It gave hard surges and rough idle. I also noticed that the voltage meter. It was like it was draining power from the battery. I continued to drive it, in hopes if I just get the gas run through the engine, it would smooth out. It did smooth out a little bit and only gave a surge when accelerating from dead stop. It finally stalled and lost power while sitting in line at a redlight. The computer is not throwing any codes so I'm not really sure what to hit next. Keep in mind that this probably my 3rd alternator since I bought the car in Oct. of '09.
