I have a similar problem. When the CEL came on the P-code was P0446. It starts right up like normal but after running for 15-20 minutes then the car just shuts off. You have to wait awhile for it cool down & then it’ll start right back up again but then it’s the same thing all over again.

There’s a high pitched squeal under the front right fender which is where the EVAP Canister is. Can a faulty “EVAP Canister Shutoff Valve” turn the car off while it’s running?

I’m thinking that I should replace #’s 2 & 6 before attempting #1: http://www.renntech.org/forums/index.php?app=core&module=attach&section=attach&at tach_rel_module=post&attach_id=8262

1 - EVAP canister purge valve
2 - EVAP canister
3 - Purge air
4 - Tank
5 - Tank pressure sensor
6 - Shutoff valve
7 - Operating purge valve
8 - To intake manifold
9 - Vacuum control valve

Any thoughts or ideas are greatly appreciated.

Thank you,
