Lost power and died on road, cranks, no start, compression good,fuel pump ok...

What is your question?

Mother-in-law driving, car came to a stop and died at light after exiting freeway, restarted and ran for another minute until loosing power and stopping. She told me the oil light came on. I have verified spark with timing light and with plug removed. Did a compression test and all was OK. Oil full and clean, checked for excessive blowzy when cranking - all OK. Opened throttle and sprayed starting fluid and it didn't even try to start. Pulled plate under rear seat and verified fuel pump is receiving power/running as it should, but have not tested pressure or output. Not too familiar with Toyotas, not sure what should be tested next...Any help appreciated.
