Diagnosing error codes

While driving normal freeway speed, sixty five mph, sudden loss of power, engine light, battery light, oil light, VT-4 light all illuminated at the same time. The engine did not stall but lost power.
Pulled off the road and did a visualization of serpentine belt or anything that seemed obvious. Tried to restart, starter just spun but would not ignite. Had it towed home, plugged scanner tool in. Gave me two separate PO3044 (CPS Sensor) codes and a P1129 (MAP sensor) code. Did a partial view look(opened top cover as much as possible without removing pulleys) at driving belt, was still connected. Looking for any opinions of what could have caused this.
