Icon2 01 Civic EX Wont Start... Electrical Issues I beleive... Need HELP!!!

I have a 2001 Honda Civic EX with 251,200 miles (bone stock) and the other day I was driving and the heat shield on the front exhaust manifold broke off and set off a CEL and Battery light. I ran the codes and got the following...

P0141 Oxygen Sensor Heater Circuit Bank 1 Sensor 2
P0135 Oxygen Sensor Heater Circuit Bank 1 Sensor 1
P1298 Electrical Load Detector (ELD) Voltage High
P0500 Vehicle Speed Sensor

After a day of driving it I went out to start it and it didn't start. I jumped it and ran fine but then died a few mins later. I noticed my dash lights, tachometer, speedometer and radio all shut off then the car died. I replaced the alternator and didn't seem to help. I replaced the battery and it fired right up I drove it to work about 8 miles away and on the way home when i hit my brakes my radio died and dash died again. My Battery light is off now but CEL is still on obviously. I addition to replacing the battery and alternator I replaced the 3 ground wires with 4 gauge wire but didn't help either. I only replaced them cause i had the supplies and the old ones were in rough shape.

I'm running out of ideas and thought id reach out to my fellow Honda-tech members for help. Any info or suggestions would be greatly appreciated

Dave

Have you tried getting the new codes?
I'd check for loose connections on the battery terminals.
