Make sure your ignition key tumbler is not loose and shutting off ignition switch when hitting a bump. Too many keys (too much weight) on the keyring can damage tumbler. Wiggle key around in "ON" position while idling to see if it shuts off engine. Check for other loose wiring that may cut-off ignition signal or circuit. Check fuel supply: fuel pump relay (suddenly no fuel pressure, starving engine).

The windows on a Chevy Blazer may not roll down if the power window mechanism has been damaged or broken. This can be repaired through a reputable mechanic.
A blown fuse could be the reason the window will not go down on your 1988 Chevy Blazer. Another possibility is that the switch is worn out or has a loose, broken, or corroded wire.

it is more than likely the fuel evap system my 97 Chevy blazer studders when accelerating.With a full tank after it gets down past 3/4 of tank runs like a champ.
I had the same problem. My 2000 Chevy Blazer would do this when I would slow down. I could not always tell if the car was at idle but after changing fuel filter, fuel pump, IAC, Ignition switch, transmission service, complete tuneup, modules and the works nothing worked. It turned out to be the crank sensor. It has not turned off in a good while now so I am thinking that was indeed the problem.
