Aircraft
I was in cruise and on autopilot for the past few hours. I was handed off to another controller with ZZZ center. He was so busy I could not break in to establish contact. After a few minutes of trying I pressed IDENT so he would know I was with him. I finally got through and was switched to another controller.Checking my instruments my airspeed was very slow; 70 knots. I checked my RPMs and it was at 2;500. I assumed my pitot static tube was blocked. I checked to make sure my pitot heat was on. Next; I checked my engine analyzer.  All cylinders were cold. I switched tanks and turned on the boost pump and ALT air. Note: Mooney Ovation has an automatic alt air system that opens with any blockage.There were never any signs of icing. This aircraft is certified for Known Ice (FIKI).All within seconds I was in an unusual attitude and in IMC. With no power; in IMC; and in an unusual attitude; I requested assistance. I have been flying for more than 20 years and never had required immediate assistance.  I was focused 110% on flying the plane. The Autopilot was off. I pushed forward to gain airspeed in case I was in a spin; then leveled the wings and asked for vectors to the nearest airport.  ZZZ was 10 miles behind me. The controller was switched to another frequency.  He was fantastic. I was on best glide speed direct to ZZZ.  I notice I was getting some power and shortly my engine was running normally. Even though everything was operating normally; I flew a VFR approach to ZZZ1 for a precautionary landing. I wanted to have it looked at by an A&P mechanic.The mechanic took off the cowling with my help.  He felt everything looked normal and operational. He noted that the engine had good compression.  His recommendation was to go to a test area and run up the engine to full power a few times. All appeared normal. I fuel up with fuel and continued my flight the following day. It flight was uneventful; but I stayed in VFR conditions as a precaution.
Pilot reported loss of all Pitot/Static air systems in IMC; requested immediate assistance and diverted to a precautionary landing.
