About every ten mins of driving my oil pressure gauges will suddenly drop all the way to zero. Not a slow drop but a split second drop and the check gauges light comes on and a Ding Ding Ding. It stays at zero for maybe a second or 2 seconds at the most then goes right back to normal. I'm no mechanic but I figure one of two things. Oil pump shuts off for a second then pops right back on....if that's even possible. Or the sensor that measures the oil pressure is failing and is going in and out. Anybody had this problem or ideas of where I should I start. Thank you in advance
