I solved my problem and am sure it will help you as they acted the same.
The trouble is in the electrical portion of the ignition switch mounted on the top of the stearing column, under the dash and above the dimmer switch. At least that is the way my 91 is. The switch has one section that is a direct power feed to the fuse box where it supplys the 4 wheel drive, heater, panel gages, and stop lights.
You will have to drop the cover under the column and remove the column support bolts, which will let it drop down a bit (on non adjustable column) to allow limited access to the switch. It will take small hands and patients. The switch is only about $22.00
Yours may be intermittant now but will soon fail totally and you won't like it.
Good Luck and God Bless
