Car cuts out while driving

[safirenside]

Alright so my car has a fresh rebuilt motor with 380 miles on it with all new sensors. after about 20 mins of driving it starts to cut out i see the rpms drop300 or 500. it mainly does it on the highway average speed of 60mph. anyone have any ideas what could be causing this problem???

map sensor. my old 420a did that too and i replaced plugs, both o2's, wires, coil pack, then come to find out it was the map sensor.

Check the harness by the cam sensor running along the side of the head. It often rubs through on many cars in that area.
