Thanks for your input folks, It was a battery issue, fresh off the charger i unloaded a truck, 1.5 hours into it the problem started to occur, battery volts dropped at times to 27.9 volts as drive cut out. While parked immediately after battery volts slowly came up to 34.5 or so, but, within a few minutes of use back to square one. I put on charge for.75 hour and it was good for another hour before the voltage dropped enough to cause the failure.
