2002 GMC Sierra 1500HD SLE - Intermittent Stall Issue
I've had ongoing trouble with this '02 Sierra 1500HD. It starts and runs
strong most of the time, but once in a while it will suddenly stall while in
motion. It has happened about 6 or 7 times over a few hours worth of
driving. It will sometimes be accompanied by power locks cycling and/or a
ding from the dash, and/or the digital gear indicator displaying 2nd gear
regardless of shifter position (it is not the dial type indicator). It will crank but
not start, usually for just a few minutes, then start up strong as if nothing
happened. Removing key and reinserting does not seem to have an effect.
I am led to believe this is a computer issue because of the odd dash
behavior, but I don't want to repair or replace without being confident. Could
a reset also help? Other possible causes?
