1995 Poniac Bonneville dies while driving.?

could be the cam sensor or the module giving up on you

General Tune-up, Change Fuel Filter, Clean Throttle Body & Injectors, Sounds like the Alternator is going Bad, Condition of the Battery; 3 1/2 to 4 1/2 Years Old or looks Swollen on the sides replace it! May need to Replace Belts! Steam Clean Engine!

I have a 1997 Pontiac Montana that was dying on me at strange times last year. Seemed like a battery problem, but the battery checked out fine. Dealership wanted to charge us $300 to look at and fix.

My husband finally took a look at the cable that leads from the battery to the starter. It was dirty and loose. He cleaned it and then tightened the bolt and that fixed the problem - for free!

I think we are on the wrong track here.

Sounds like the engine is dieing out and causing the voltage changes.

Maybe fuel filter?

Maybe the fuel pump?

Is there a accessory (air conditioner) seizing up and stopping the engine?

I think it's the alternator too.

Ask how much they charge for that diagnostic test before you get one. I've heard they can cost about $100.

check the alternator it could be running on it or charging sometimes, may be a short if it only does it sometimes, had this problem on a chevy blazer

TAKE IT TO A SHOP THAT HAS THE LATEST AND NEWEST DIONOSTIC MACHINE AND THAT WILL TELL YOU WHATS WRONG WITH THE CAR BELEAVE ME OK I KNOW IT WILL WORK WE DO IT EVERYDAY FOR THE LAST 13 YRS
