My DRZ wants to die every time I cross water as shallow as 1ft. If I rev it high it keeps going, but yesterday I had it in about 2ft of water and it died completely and wouldn't start up till I got it out of the water, even though I never let off the throttle while in the water. Pipe, battery, airbox were all above water. This has to be happening from the water splashing onto something. Shouldn't be electrical since it bogs before it dies. Any ideas?
