The gauges going dead has me stumped. If it was just shutting down to protect itself then then I don't thing the gauges should go dead first. Check a couple things while we wait for some other minds to chime in.
Battery cables clean on both ends
All the fuses, relays are seated good and have no corrosion.
Pump drive belt(inside the large plastic cover on the left side of the engine) isn't broke or loose.
