So I own a 2002 tl-s and ive been having an isuue thats been getting worse and worse. The engine will stall randomly Its stalled when in park and on the highway doing 70+. the engine goes out as does the power steering. But all the accessories stay on. Ive replaced the ignition switch and i was sure thatd solve it but i stalled out on the way to work again today. Another possibility is the fuel pump/main relay. But it seems like most people who have had that issue just cant start their car. Mine always starts but dies while driving. Then if i try to start it back up the engine will crank but not start. I let it sit for 10 minutes and it starts back up again. Any help would be much appreciated!

 

ck the relay board back side for solder issues, ck DIY or threads on the subject for pics and help

 

Update:replaced the fuel pump relay. The old one definitely looked a little brown in some spots and one of the solder joints definitely looked suspicious/corroded. Hopefully it worked

 

Seems to have done the trick. Heres the old relay

 

did you remove the board and examine the part the relay connects too?
bad solder one place = ....
