Hi, I have a 1998 Cali EV, it’s been running fine but on the last two journeys it suddenly lost power after about 6-8 miles like it was going to cut out and I had to keep revving to keep it going with it surging power on and off, and then after a few miles of this seemed to run normal again. But this was only a short journey and did not get opportunity to see if it may re-occur. Has anyone experienced this or any ideas please

Could be water in fuel or a bad electrical connection?

Two things spring to mind, blockage of the tank breather or water contamination which can also partially block the fuel filter.

rust in the fuel system causing pressure regulator to stick open ( no pressure ) also sticks open 1 way valve in fuel pump
