Ran for a couple of minutes then the oil light came on..turn it off check oil...low from it filling the system. added oil back to full. started fine ran for a couple of min again then oil light on again. checked oil and its full. check for leaks...none bone dry. start again..idle oil light on...give a little gas goes off at 1300rpm..checked that twice then shut it off..checked for leaks again..bone dry..do not want to start again until I can figure it out. any ideas would be appricated. Oh the oil pressure sender in block is new as well.
