Ignition switch

[rfresolo]

I have been having problems with my 2000 savana 3500. i notice when i cut the steering wheel when in reverse the truck shuts off. sometimes it will lose power when at red lights. and i will have to restart the truck. i noticed today at a drive thru when i cut the wheel all the way the truck started to lose power, the volt gauge kept fluctuating between 10 and 14 and if i didnt hit the gas it would have shut off. i been reading other posts and cant find anything quite similiar to this problem. any ideas.

Ignition switch is the best probability.
