There is probably a problem with you anti lock brake system. Have it checked at your local dealership. Brakes are a problem that should never be let go.

Most definitely electrical problem. Though GM connectors are quite reliable - they sometimes get misconnected or you have a poor connection. get it cehcked.

this is most commonly a electrical problem, does the speedometer read out correctly? if not it may be depending on if this is a Autotrak model, one f the two speeed sensors, or the acuator on the front diff, put the truck in 4wd, check the front dirveline to make sure it is engaing, if not your problem is in the t-case, if it does then move to the tires, if they are not engaged you have a problem with the actuator.
in most cases i have found the actuall 2wd 4wd switch to be the problem if you find that the switch is acting slow or you need to select the gear a few times before it shifts, then replace it these are very faulty
