My 2000 Chevrolet Suburban when I drive it for about 45 minutes it seems to lose power then cut off then I have trouble starting it back up.
Answers from the Automotive Experts
Larry,
Unfortunately by your description your drive ability concern may be caused by a number of faults. One to consider is your alternator of idle air control valve may be failing. Worth a check out by your local mechanic.
I would have the charging system (alternator) inspected, and/or the cooling system. Some GM's shut off prior to overheating.
There are many possibilities for this drivability issue. It could be a charging system issue, a fuel delivery issue, or an ignition issue. Your best bet is to have this one diagnosed by a trained technician.
Hi Larry, On your 2000 Suburban, There may be a fuel problem. I would recommend having the fuel pump pressure checked first. I don't recommend driving a vehicle that shuts off and is hard to start. It could be dangerous. Good luck.
