WHAT COULD CAUSE MY TO DIE WHILE DRIVING?

1999 Jeep Wrangler • 145,000 miles

My 99 4.0 5 Spd Jeep Wrangler died on the highway while going 65mph. I tried to kick start it but it did nothing. It died as if I turned the key off. I've replaced the coil pack, distributor pick up, crankshaft pos. Sensor, ignition switch actuator pin. I've also check for corroded wires and lose grounds. The engine just cranks, but will not start. I'm not getting spark to the coil. Could the computer is bad?

Do you have any codes in the computer?

Yes, 0455 and 1389. 0455 doesn't have me concerned, because I attribute that to my gas cap, which doesn't fit 100%. But 1389 has me stumped.
