2003 Jetta.... Speedometer, gas lights, and check engine!!!

I have a 2003 Jetta, which by the way I love! Its only a 2.0 liter, but I still have fun with it! Today I was driving and the speedometer completely dropped to 0 my gas light then came on and then my check engine light came on. then all was well and then it all happened again..... Any suggestions? Please help!!!!!!

Have a dealer or shop read the codes in the ECM. It will help.
