2001 CHEVROLET SUBURBAN 2500 Engine And Engine Coolingenginegasoline Problems

BOUGHT A USED 01 SUBURBAN ON 9/10/06 IT HAS 826000 MILES ON IT. THE DAY AFTER I BOUGHT IT DRIVING DOWN THE ROAD 30 MPH, THE TRUCK STALLED. I PUT IT IN NEUTRAL, STILL ROLLING AND ATTEMPTED TO RESTART 2 OR 3 TIMES. IT FINALLY STARTED. IT HAS ALSO DONE IT AT A DEAD STOP AT THE BANK DRIVE THROUGH. THIS TIME IT DIDN'T RESTART UNTIL I PULLED THE KEY AND REINSERTED IT AND IT STARTED. AS OF TODAY 9/19/06 IT HAS DONE IT AT LEAST 7 TIMES. I TOOK IT TO CHEVROLET THEY SAID POSSIBLE CRANK POSITION SENSOR? *NM

VEHICLE WOULD DIE RANDOMLY WHILE OPERATING CAUSING LOSS OF STEERING AND BRAKING. USUALLY OCCURRED AT LOW SPEEDS (LIKE IN TRAFFIC) AND RE-STARTING REQUIRED LENGTHY CRANKING. THIS IS THE SECOND TIME THIS PROBLEM HAS COME UP WHILE I'VE OWNED THE VEHICLE WITH THE SAME CORRECTION, REPLACING THE CRANK POSITION SENSOR. I HAVE THE OLD PART. *JB

CAR WILL DIE AT HIGHWAY SPEED, LEADING TO LOSS OF POWER STEERING AND POWER BRAKING. 2001 CHEVY SUBURBAN WITH 8.1L ENGINE. THIS SOUNDS THE SAME AS OPEN COMPLAINT NHTSA ACTION NUMBER: PE06016. *NM
