I recently just started playing KSP, have about 80 hours+ of game play and still consider myself a newbie. The problem that i am experiencing now is that my engines stop functioning midburn - and by that i mean all engines, both 2nd and 3rd stage, and they wont start up again. Some background, i took 2 tourist missions that are exactly the same - orbit Kerbin, orbit Mun and orbit Minmus -, reason is, i had missions to fly by, orbit and collect data from both Mun and Minmus and told myself that i could take the tourists along and make more money out of the trip. So, i made improvements on a craft that previously used to orbit the Moon. First stage had 4 Skippers, 2nd stage with 3 Reliants and the 3rd stage with 1 Reliant - combined Dv is around 5k (which is actually more than enough). Now, here is where it gets weird (for me anyway), i completed the first tourist mission using the craft that i designed without any issues, all stages worked fine and was able to land safely on Kerbin again. Saved the game and proceeded to run the second tourist mission. Everything starts as per normal, i proceeded with my usual ascent profile (which i have to improve), completed an orbit around Kerbin and created a maneuver node for a Mun transfer. As i am burning my node for the Mun transfer (40 seconds+), midway my engines would stop working. It can't be a fuel issue because everything says i have fuel, i am puzzled, thinking that it might be some glitch or the game might be acting up i exited to my desktop and restarted the game. But lo and behold, same thing happens on my second and third retry. As checked what went wrong i noticed that all Electric Charges on all engines are ZERO, that goes for 3 Reliants on my second stage and 1 Reliant on the first stage. I tried ditching the second stage thinking it would solve it but no, same, engines wont start. As i try my fourth run on the mission, i noticed that my Electric Charge gets sapped slowly when my engines are IDLE, which i find weird because the only part on the ship that requires electricity is the Communotron16 and i haven't even activated that yet. Turning OFF/ON SAS and RCS doesnt help either. Im not sure, it has never happened before and dont know why its happening now, all along i thought Reliants didn't use Electric Charge. I haven't tried again after the 4th run, maybe i should rebuild the ship? Remove the Communotron16? Any ideas? Advise? Your thoughts would be greatly appreciated. Thanks!
