98 2.2l s10 dying while driving issues
 

I have a 98 2.2l s10 with 197,000 miles, and it seems to die while driving. While driving on the highway I hit a bump and the car shuts off like I turned it off for half a sec and kicks back on. Some times it just turns off the cluster for half a second and I I lose cruise for a minute. It only really seems to happen on the highway. Any thoughts?
