engine stalls but check engine light does not come on
 

when im driving up hill my 2001 grand marquis sumtimes stalls when i accelarate then my temp light comes on then goes off or the green o/d light blinks on and off but my check engine light does not come on and is doing it more frequently. does anybody know the problem and salution:confused:?

Seems to be a very puzzling set of circumstances involved with this problem. I would consider taking a look at your fuel pressure, and if that seems ok, I would wonder if there maybe a problem with a clogged catalytic converter that is restricting your exhaust flow?
