you may not have the right oil filter on it
i do not think that would be it,we have had the oil changed at two diffrent places and it still does it the guy i bought it from said it did the same thing to him when he bought it and he owened it for 2 years

Oil presure switch on the top back of motor.
Have the oil pressure checked, you may have a weak oil pump or an internal leak in the oil passageways. Try to eliminate low oil pressure before doing anything, then if it's OK, check the gauge and electrical circuits.
how or where can i do that?
