Similar problems? In 35 years of riding and racing - no.
Start looking at tyre condition, pressures, head and wheel bearings in that order. Plenty of online guides to show how to check them all. I'll be surprised if the fault isn't one or more of those issues, all easily remedied and comparatively cheap. In the mean time I would stop riding it, you might crash it and cause a huge repair bill or worse still hurt yourself or someone else. Good luck!
