Same problem. Replacing the cam sensor and relay switch fixed it for me.

I am having the same problem. Car was purchased 2nd hand and every conceivable repair has been made to it. I have spent approx. $2,000 in repairs but car still runs for about 20 - 25 minutes, cuts out and must cool down for 15 minutes or so before it will crank again. I noted the 3 answers and will follow up. Any other ideas about what could possibly be wrong. We have not replaced about all we can.

I just had this problem for the past few months and could not figure it out...finally, my mechanic read up on Trackers and said to me..."let's check the CRANKSHAFT"...and, he was absolutely correct! So, CHECK YOUR CRANKSHAFT! Also, I already had replaced my O2 sensor previously...best of luck to you!
