1995 Pontiac Grand Am with a 2.4 liter quad four engine. Mileage about 180000. Cold cranks and runs fine, but after about ten minutes of driving the engine stalls, especially upon acceleration. Just cuts off like a light. Then will not re crank for a few minutes. It's not running hot or missing or running rough, just stalls out. Could it be the air oil setarator? It appears to be cloged with creamy brown grease. Also, the two hoses in the front are cracked a little and the larger hose on the back is rotten and split open. There is a flat copper band inside that hose and a sensor attached to it.
