2001 8.1 litter 4wd stalling intermittently

[sst98]

As my wife drives this vehicle with my kids in, I'm searching for an answer to likely solutions for this, I've had it into the mechanic 4 times now, and no luck. Problem is too intermittent.

I've seen 2 other posts talking about the crankshaft sensor and the fuel pressure regulator issues.

The suburban has 49k miles.

Thanks for any help you can provide.

Just had the CPS replaced in my 2001 GMC Yukon (8.1) yesterday after experiencing random stalls while driving and not starting. I'll update this in a couple weeks with results. Since there were no codes set I just took this potential solution based on posts seen.

I own a 2001 Chevrolet Suburban ¾ 4x4 with about 88,000 miles on it's 8.1 L engine it. About a week ago, I was driving down the road and it just shut off! No power! No power steering, no power brakes, no engine! Thank goodness I was not on a busy highway! A day later, it happened again! Fortunately, I was, again, not a busy road. I looked up the problem on the internet and suspected that it was the crankshaft position sensor. I also found out that there is a recall for 2001 Suburbans for this very part! I took it to the dealer and when they put in my VIN number, amazingly, my truck did not qualify for a free fix! I have to PAY $450 to fix this part that is obviously a problem! This part goes bad and you can DIE! And you never know when it will start going bad! WHEN will it shut down the first time? It's like Russian Roulette! We own 3 Chevys and will NEVER buy another one! I hope it was worth the $450 they made to lose a customer for life!

Note: If yours is not covered also, please call the National Highway Traffic Safety Administration at 1-888-327-4236 and filed a complaint and they MIGHT include more VIN numbers.
