I had my battery and alternator tested the day of the 2nd time dying, they both tested perfectly fine. Could it be the fuel pump or timing belt?

I recently purchased a 1996 LS400 with 127k miles. While the car was on, it died on me and it would not turn back over. I have had this problem twice now, the first time, I was parked for about 5 minutes after a short drive when it had died, I was able to get it jumped and it ran well for 2 days. The second time, I had come to a stop at a red light and as i was about turn it died on me again. If anyone knows the problem or has any ideas on how to fix this please let me know.
