Aircraft
A BE35 Bonanza departed ZZZ at approximately XA:30 for a direct flight to ZZZ1. At approximately XC:15 I diverted to ZZZ2 upon observation of a continual spray out of the  cap of the right main fuel tank. I landed and had minor greasing of cap and subsequently departed to ZZZ1 (destination). At approximately XD:40 a sudden and violent turn and descent occurred. I immediately controlled the yoke to reestablish level flight; searched for handle to move gas flow from right to left main and [advised] ATC. As control and checks were executed I decided to divert to ZZZ3. With the plane maintaining altitude and power I executed a non-eventful landing at ZZZ3 after 2 attempts. Once on the ground there was a leak of gas from under the engine.My major advice is to be aware that a situation can develop in a number of seconds and keep a record of all fuel used and time remaining.
BE-35 pilot reported diverting due to a loss of fuel out of the right fuel cap; then diverting again later after losing power associated with a fuel leak.
