97 exped loss of oil pressure at hwy speed
At hwy speeds (only) oil pressure needle bottoms out a few times then goes to zero, but only after about 10 min of driveing. At low speed light to light driving, pressure runs normal. Pressure is good when checked with mechanical gauge. Has 126k miles. 5.4 , 1997. Pressure sensor checked good. What do ya'll think?
