Without symptoms will just quit running while driving. No indication to start for 5 to 10 minutes will start quickly and run perfect. Has no special time or event may run for 1/2 up to 2 days before stalling. Then after 5 to 10 min. will start and run great. Had some idle problems today tho. Does not show a code running or when stalled. Replaced fuel pump and ignition module to no avail. Full of gas no over heating.
Engine stalls intermittently. on 1999 Pontiac Bonneville

Them there crank sensor thingamajigs gives some kinds of troubles like dat sometimes... i seed one do it one times!.., And i fix it all by myself by golly...., However i had a proffesional scanner that helped out a BUNCH!... hint..hint...
COMMENT by Sorensond on June 20, 2014
Professional scanner has been used repeatedly. No code running or while refusing to run. Like your accent was it hard to write like that or does it come normal?
COMMENT by pushrod on June 20, 2014
Hillbilly slang from the Blue Ridge mountains of VA. Scanner 'live data' is what needs to be viewed for crank signal from sensor.... next time it acts up... Check for ignition fire also .... This sensor is behind the crank balancer (pulley) and requires it to be 'carefully' removed as the signal trigger is attached to it!!!... Once removed, check it also for deformed trigger fins.....Or get some hands-on help... don't know your skill level or toolbox arsenal.... This would be 'my' next guess at it if i were doing the repair!... For what it's worth...
Has new fuel pump,new coils, checked ignition module it's OK, No check engine light, no codes on scanner. When it quits pouring cold water or drink, Pepsi, it starts immediately and may run for a day or a day and half and sometime less. Sometimes it quits a couple of times or stumbles a few times after quitting. Waiting 10 to 15 minutes every time it starts immediately and runs strong on all cylinders. Maybe Crank Shaft sensor is it. When it quits is like cutting off the ignition. No warning just quits.
Pouring water on what exactly???... Module and coils???
Yes directly on the coils and of course ignition module.
No brainer.... ... Replace the module!!!!!

Finally took it to a GM dealer, it was the Crankshaft Position Sensor. Cured thanks for all of the help.

ANSWER by jfranks83 on July 01, 2015
hes right you need to change your crank sensor
The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.
The crankshaft position sensor may fail causing the engine to stall intermittently, the Check Engine Light may or may not illuminate.
when car is driven and gets to operating temp. it intermittantly wont start and occasionally stalls
