dashborad indicators

I have a 1995 Tahoe which recently starting having some weird problems. I was driving along at 55 MPH and felt a very slight momentary jerk, on the dash I saw my brake light, seatbelt light and airbag light come on in about the same time. Continued on and nothing seemed to be wrong. Next day, started up like normal, and the motor just shut off. Started back up and continued onto work and nothing seemed to be wrong. I got off work, started up and just about to pull away and the truck died again. Started back up, drove home and about 2 miles from home I felt the same slight jerk, and again the brake light, seatbelt and airbag lights all came on momentarily but it never shut down.

I don’t know where to start looking for a problem since all items (brake, seatbelt and airbag) don’t seem to be related. Is there anyone that has any ideas where to start to troubleshoot a problem like this?

stop by an autozone and have them check computer fault codes
