I sprayed degreaser on my engine, think I might.

I sprayed degreaser on my engine, think I might of got something wet. First notion was maybe moisture in the dis cap, changed the cap rotor and wires, still having problem. The truck starts and runs, then putting it into gear and taking off does fine, when I start to stop I push in the clutch and put it into neutral I hear a clicking sound on the passenger side and the truck dies, starts right back up but keeps doing it when Im stopping. Is this the saftey switch?
