Help!! '98 2.2L S10

Here is the problem...my S10 engine shuts down on me. I've had just about every sensor and filter on it changed in the last 2 wks. I have had the alternator and battery changed twice. So today I went to an electrical shop to get the codes pulled. $50 bucks later the PCM is giving a P1632 code. Basically my truck thinks I am stealing it. Is there any way of resetting or fixing this problem?
