2000 cirrus 4cy stalling problems
 

my car has 200k on it and has been running fine tell a couple weeks ago it started stalling at highway speeds sometimes once in a great while and other times alot since this started to happend when i turn the cruse control on the light comes on but when i push the botton it does not work not sure this is related or not. i had it in a shop and the only thing he found on the computer as far as codes is the sencer behind the caddy that we replaced the car worked better but the issue still was there then 2 days ago it got a lot worse and this morning it would not start turns over fine just will not start. i checked the spark on 2 wires and it has a good spark and over 4 hours later it still will not start. Last night and since this started i can go from 0 to 70 with no problems but the stalling happens at normal driving speeds the fuel pressure is at factory specs. not sure what to do with it the garage says they will keep looking at it to find the issue at $76 an hour. please help i am lost.

i forgot to say that my check engine light has not came on at all when the car is stalling
