My truck runs and starts but goes electrically dead after running for 5-10 min, no gauges, no horn, no windows, no locks, no flashers, no radio nothing electrical, but continues to run for another 5-10 min then dies completly. If I let it set for an hour or so then it restarts with full power.

Start your check with the battery terminals
clean and tighten
start engine and check charging system and alternator
volts should be at about 14V with engine running

Thank you, I did check the battery terminals and cables. They are tight and clean.

There was aslo a beeping when the electrical went. Four, above normal volume, beeps repeated three or four times after I lost the dash board and electrical. My wife said it did the same thing to her as she pulled into the parking at school.
