2004 Saab 9-3 repair Question 4 cyl Automatic 70,000 miles

Randomly the "immobilizer failure" message comes on. After that happens and I shut off the car, I have to have it jumped started to get it started, and sometimes its not the first time I start the car after the message, its only if I leave the car off for a day or two.

It doesnt appear that the car actually needs a charge, cause it starts immediately when you hook up the cables. I replaced the battery already.
