So I've had the propane out on the trails twice with no issues,(trailered)-- yesterday I decided to drive it in to work,all went fine, went to go home and about 1/2 way home it lost power and would only run at low rpm's. Noticed the connection at the tank was freezing. Seemed to be all right for a couple more minutes then again started to stall. Switched tanks and no problem? Leak at tank?? Seemed to happen only when wot on the freeway,take my foot out of it and would be fine?? By the way the tank that the fitting froze up on was filled on the way to work. Any help would be appreciated.
