Daughters car now off the road as I had to give up on it back in the brutal winter here. It starts and runs perfectly until it warms up, ambient temp about 65 this means 3 minutes, then it completly lacks power and has a surging idle ( almost stalls then recovers). Seems to be a fuel delivery problem as it is not choking out more like a lack of fuel. Let it cool down and runs good again until it warms. O2 sensor and cat were new last fall. Air mass meter swapped out no change.
Thanx for your advise.
