newbie needs help! i have a 2000 bonne with a 3.8 and 70k miles. last week she started stalling out at slow speeds, no misfire or chuging ( just died like the ign. key was turned off ) starts right back up . did this 4-5 times . next day she dies on the highway , stumbles to start but does. made it another 2 miles and die again. appears to do this after about 15 min. from start up. put her in the shop replaced the crankshaft sensor, ign. switch, idle air and engine control modules. still having trouble
Add your year and trim to your sig so we can help you easier.
Does the service engine soon light come on? are there any codes available?
Check the under hood fuse panel, make sure its tightend down well.

this is 2000 bonneville se with a 3.8. no check engine light or codes stored . no fuel press. drop at time of stalling. it almost seems as if all electrical power just cuts out. all gauges drop . car starts right back up. only time it didn' t was on the highway and it was stumbling so i think it just loaded up.
I wonder if it could be a bad fuel sending unit? I have heard of them failing when they warm up, but not sure if it would throw codes or not. Your miles are low enough that I would think it would not be the prob.
