Narrative:

On taxi, tower's clearance to me was to 'taxi to runway 29, hold short runway 25.' approaching hold line to runway 25, 2 separate events occurred: 1) truck with yellow flashing lights on taxiway passed my left wing traveling toward tail of aircraft. 2) as I turned to see truck with flashing lights, I noticed 2 circuit breakers popped with associated caution lights. My attention was directed to circuit breakers and telelite panel and 1 second later I stopped the aircraft. The nose of act was now on hold line (about 2 ft over). I was about to tell copilot to report this to ground control and then heard tower send a C172 around on base to final. His call was that a 'citation jet' had crossed the hold line. As soon as the C172 rolled out on final, at 600 ft AGL he went around without incident. Tower told us to continue to taxi. Upon landing, I tried to contact tower personnel to explain the slight incursion over hold line but no one returned call. My failure to stop aircraft before hold line was caused by the truck distraction plus the popped circuit breakers. I had every intention to stop.
