Electrical gremlins?
Hello. I have a '96 LT4 with 60,000mi. I was just driving and the car hesitated about three times, then the tachometer stopped working and the two ASR lights came on, Service ASR and ASR Off. Went home, turned the car off and tried to restart it. Was very hard to start which never happens. Got it started and the same lights and no tach, this time the SES light was on! Is it possible it's just a fuse? I tried to check the fuses but I can't find a fuse for the tach or ASR. Anybody have this problem? Any suggestions? Any help would be appreciated. Thanks.
Update; All lights have gone off and the car runs fine! I have noticed similar things going on. Like the SES light going on for a day or two and then going off. The LTPWS light and the Service LTPWS lights going on and off. I think the ASR issue might come back after driving for a while. We'll have to wait and see.

I would be checking for faulty ground connections first.

I did check the battery and the positive side tightened up about a quarter turn. Gonna keep my fingers crossed....

On the bell housing behind the oil filter.
On the block slightly toward the passenger side below the throttle body.
