Sounds like you are on track to finding an intermittent wiring gremlin. The pump pulls around 18 amps @ 12v so any kind of bad connection is going to halt the motor. i would guess one of the wires that jumps +vdc across the switches has a bad connection. Hard to say Without seeing how it's wired. A volt meter will tell you voltage drop across the terminals when depressing the switches. From there you should be able to back into the connection issue. you can also throw a new switch array at it and see if that fixes he issue
