I own a pair of 94 Prowler 2ups 440 EFI. On a few seperate occansions both machines have suddenly quit when running about half throttle after being warmed up. In each case I let them sit far a few minutes and they restart and run fine again. Both have GOOD batteries so that's not the problem. Has anyone else experienced anything like this? My mechanic suggested I clean the injectors and see if that helps.
