it could be the alternator with a bad diode, a light remaining on that you cannot see, any other accessory pulling down the battery. also, have the battery load tested to verify it is not sulphates.

AS FAR AS 5 HOURS OF OPERATION

CHARGE THE BATTERY---SNATCH ALL THE WIRES OFF OF THE ALTERNATOR

LET IT SIT OVERNIGHT

ATTEMPT A CRANK-UP NEXT MORNING---IF IT CRANKS JUST FINE, MOST LIKELY, IT IS THE ALTERNATOR AS ASEMaster6371 SUGGESTED

IF NOT, HAPPY HUNTING!
