swapping PCM's in a 1997 Jeep Grand Cherokee

I am having the "stalling/cutting out" problem with my 1997 Jeep Grand Cherokee Larado. Tried backing out the two cover screws on the PCM, but that didn't change anything. The previous owner replaced the distribtor cap, all spark plug wires & plugs, new battery and new battery connectors and finally the Crankshaft Position Sensor before he gave up and sold the vehicle. I have a spare PCM from a 1998 Jeep Grand Cherokee Larado. They both have the Straight-6 engine. Can I swap them? They look the same. I have seen the posts about getting a re-manufactured PCM with your VIN flashed into the new one for about $250. Do I need to do that? Hate to spend the cash if I don't need to.
